 A GitHub action to create a pull request for changes to your repository in the actions workspace.
 
-Changes to a repository in the actions workspace persist between actions in a workflow.
-This action is designed to be used in conjunction with other actions that modify or add files to your repository.
+Changes to a repository in the Actions workspace persist between steps in a workflow.
+This action is designed to be used in conjunction with other steps that modify or add files to your repository.
 The changes will be automatically committed to a new branch and a pull request created.
 
 Create Pull Request action will:
 
-1. Check for repository changes in the actions workspace. This includes untracked (new) files as well as modified files.
-2. Commit all changes to a new branch. The commit will be made using the name and email of the `HEAD` commit author.
-3. Create a pull request to merge the new branch into the currently active branch executing the workflow.
+1. Check for repository changes in the Actions workspace. This includes:
+   - untracked (new) files
+   - tracked (modified) files
+   - commits made during the workflow that have not been pushed
+2. Commit all changes to a new branch, or update an existing pull request branch.
+3. Create or update a pull request to merge the branch into the base&mdash;the branch checked out in the workflow.
 
-Note: Modifying a repository during workflows is not good practice in general.
-However, this action opens up some interesting possibilities when used carefully.
-This action is experimental and may not work well for repositories that have a very high frequency of commits.
+## Documentation
+
+- [Concepts, guidelines and advanced usage](docs/concepts-guidelines.md)
+- [Examples](docs/examples.md)
+- [Updating to v7](docs/updating.md)
+- [Common issues](docs/common-issues.md)
 
 ## Usage
 
-In addition to the default `GITHUB_TOKEN`, the action requires a `repo` scoped token in order to commit.
-Create one [here](https://github.com/settings/tokens) and pass that as a secret to the `REPO_ACCESS_TOKEN` environment variable.
+```yml
+      - uses: actions/checkout@v4
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+```
+
+You can also pin to a [specific release](https://github.com/peter-evans/create-pull-request/releases) version in the format `@v7.x.x`
+
+### Workflow permissions
+
+For this action to work you must explicitly allow GitHub Actions to create pull requests.
+This setting can be found in a repository's settings under Actions > General > Workflow permissions.
+
+For repositories belonging to an organization, this setting can be managed by admins in organization settings under Actions > General > Workflow permissions.
+
+### Action inputs
+
+All inputs are **optional**. If not set, sensible defaults will be used.
+

+
+#### token
+
+The token input defaults to the repository's `GITHUB_TOKEN`.
+
+> [!IMPORTANT]  
+> - If you want pull requests created by this action to trigger an `on: push` or `on: pull_request` workflow then you cannot use the default `GITHUB_TOKEN`. See the [documentation here](docs/concepts-guidelines.md#triggering-further-workflow-runs) for further details.
+> - If using the repository's `GITHUB_TOKEN` and your repository was created after 2nd February 2023, the [default permission is read-only](https://github.blog/changelog/2023-02-02-github-actions-updating-the-default-github_token-permissions-to-read-only/). Elevate the [permissions](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/controlling-permissions-for-github_token#defining-access-for-the-github_token-permissions) in your workflow.
+>   ```yml
+>   permissions:
+>     contents: write
+>     pull-requests: write
+>   ```
+
+Other token options:
+- Classic [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) with `repo` scope.
+- Fine-grained [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) with `contents: write` and `pull-requests: write` scopes.
+- [GitHub App tokens](docs/concepts-guidelines.md#authenticating-with-github-app-generated-tokens) with `contents: write` and `pull-requests: write` scopes.
+
+> [!TIP]  
+> If pull requests could contain changes to Actions workflows you may also need the `workflows` scope.
+
+#### branch-token
+
+The action first creates a branch, and then creates a pull request for the branch.
+For some rare use cases it can be useful, or even necessary, to use different tokens for these operations.
+It is not advisable to use this input unless you know you need to.
+
+#### commit-message
+
+In addition to a message, the `commit-message` input can also be used to populate the commit description. Leave a single blank line between the message and description.
 
 ```yml
-    - name: Create Pull Request
-      uses: peter-evans/create-pull-request@v1.1.0
-      env:
-        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
-        REPO_ACCESS_TOKEN: ${{ secrets.REPO_ACCESS_TOKEN }}
+          commit-message: |
+            the first line is the commit message
+
+            the commit description starts
+            after a blank line and can be
+            multiple lines
 ```
 
-#### Environment variables
+#### delete-branch
 
-These variables are all optional. If not set, a default value will be used.
+The `delete-branch` feature doesn't delete branches immediately on merge. (It can't do that because it would require the merge to somehow trigger the action.)
+The intention of the feature is that when the action next runs it will delete the `branch` if there is no diff.
 
-- `PULL_REQUEST_BRANCH` - The branch name. See **Branch naming** below for details.
-- `COMMIT_MESSAGE` - The message to use when committing changes.
-- `PULL_REQUEST_TITLE` - The title of the pull request.
-- `PULL_REQUEST_BODY` - The body of the pull request.
+Enabling this feature leads to the following behaviour:
+1. If a pull request was merged and the branch is left undeleted, when the action next runs it will delete the branch if there is no further diff.
+2. If a pull request is open, but there is now no longer a diff and the PR is unnecessary, the action will delete the branch causing the PR to close.
 
-#### Branch naming
+If you want branches to be deleted immediately on merge then you should use GitHub's `Automatically delete head branches` feature in your repository settings.
 
-The variable `PULL_REQUEST_BRANCH` defaults to `create-pull-request/patch`.
-Commits will be made to a branch with this name and suffixed with the short SHA1 commit hash.
+#### Proxy support
 
-e.g.
-```
-create-pull-request/patch-fcdfb59
-create-pull-request/patch-394710b
+For self-hosted runners behind a corporate proxy set the `https_proxy` environment variable.
+```yml
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        env:
+          https_proxy: http://<proxy_address>:<port>
 ```
 
-#### Ignoring files
+### Action outputs
+
+The following outputs can be used by subsequent workflow steps.
+
+- `pull-request-number` - The pull request number.
+- `pull-request-url` - The URL of the pull request.
+- `pull-request-operation` - The pull request operation performed by the action, `created`, `updated`, `closed` or `none`.
+- `pull-request-head-sha` - The commit SHA of the pull request branch.
+- `pull-request-branch` - The branch name of the pull request.
+- `pull-request-commits-verified` - Whether GitHub considers the signature of the branch's commits to be verified; `true` or `false`.
+
+Step outputs can be accessed as in the following example.
+Note that in order to read the step outputs the action step must have an id.
+
+```yml
+      - name: Create Pull Request
+        id: cpr
+        uses: peter-evans/create-pull-request@v7
+      - name: Check outputs
+        if: ${{ steps.cpr.outputs.pull-request-number }}
+        run: |
+          echo "Pull Request Number - ${{ steps.cpr.outputs.pull-request-number }}"
+          echo "Pull Request URL - ${{ steps.cpr.outputs.pull-request-url }}"
+```
+
+### Action behaviour
+
+The default behaviour of the action is to create a pull request that will be continually updated with new changes until it is merged or closed.
+Changes are committed and pushed to a fixed-name branch, the name of which can be configured with the `branch` input.
+Any subsequent changes will be committed to the *same* branch and reflected in the open pull request.
+
+How the action behaves:
+
+- If there are changes (i.e. a diff exists with the checked-out base branch), the changes will be pushed to a new `branch` and a pull request created.
+- If there are no changes (i.e. no diff exists with the checked-out base branch), no pull request will be created and the action exits silently.
+- If a pull request already exists it will be updated if necessary. Local changes in the Actions workspace, or changes on the base branch, can cause an update. If no update is required the action exits silently.
+- If a pull request exists and new changes on the base branch make the pull request unnecessary (i.e. there is no longer a diff between the pull request branch and the base), the pull request is automatically closed. Additionally, if [`delete-branch`](#delete-branch) is set to `true` the `branch` will be deleted.
+
+For further details about how the action works and usage guidelines, see [Concepts, guidelines and advanced usage](docs/concepts-guidelines.md).
+
+#### Alternative strategy - Always create a new pull request branch
+
+For some use cases it may be desirable to always create a new unique branch each time there are changes to be committed.
+This strategy is *not recommended* because if not used carefully it could result in multiple pull requests being created unnecessarily. If in doubt, use the [default strategy](#action-behaviour) of creating an updating a fixed-name branch.
+
+To use this strategy, set input `branch-suffix` with one of the following options.
+
+- `random` - Commits will be made to a branch suffixed with a random alpha-numeric string. e.g. `create-pull-request/patch-6qj97jr`, `create-pull-request/patch-5jrjhvd`
+
+- `timestamp` - Commits will be made to a branch suffixed by a timestamp. e.g. `create-pull-request/patch-1569322532`, `create-pull-request/patch-1569322552`
+
+- `short-commit-hash` - Commits will be made to a branch suffixed with the short SHA1 commit hash. e.g. `create-pull-request/patch-fcdfb59`, `create-pull-request/patch-394710b`
+
+### Controlling committed files
+
+The action defaults to adding all new and modified files.
+If there are files that should not be included in the pull request, you can use the following methods to control the committed content.
+
+#### Remove files
+
+The most straightforward way to handle unwanted files is simply to remove them in a step before the action runs.
+
+```yml
+      - run: |
+          rm -rf temp-dir
+          rm temp-file.txt
+```
+
+#### Ignore files
 
 If there are files or directories you want to ignore you can simply add them to a `.gitignore` file at the root of your repository. The action will respect this file.
 
-## Example
+#### Add specific paths
 
-Here is an example that sets all the environment variables.
+You can control which files are committed with the `add-paths` input.
+Paths should follow git's [pathspec](https://git-scm.com/docs/gitglossary#Documentation/gitglossary.txt-aiddefpathspecapathspec) syntax.
+File changes that do not match one of the paths will be stashed and restored after the action has completed.
 
 ```yml
-    - name: Create Pull Request
-      uses: peter-evans/create-pull-request@v1.1.0
-      env:
-        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
-        REPO_ACCESS_TOKEN: ${{ secrets.REPO_ACCESS_TOKEN }}
-        PULL_REQUEST_BRANCH: my-patches
-        COMMIT_MESSAGE: Auto-modify files by my-file-modifier-action
-        PULL_REQUEST_TITLE: Changes from my-file-modifier-action
-        PULL_REQUEST_BODY: This is an auto-generated PR with changes from my-file-modifier-action
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          add-paths: |
+            *.java
+            docs/*.md
 ```
 
-This configuration will create pull requests that look like this:
+#### Create your own commits
 
-![Pull Request Example](pull-request-example.png?raw=true)
+As well as relying on the action to handle uncommitted changes, you can additionally make your own commits before the action runs.
+Note that the repository must be checked out on a branch with a remote, it won't work for [events which checkout a commit](docs/concepts-guidelines.md#events-which-checkout-a-commit).
+
+```yml
+    steps:
+      - uses: actions/checkout@v4
+      - name: Create commits
+        run: |
+          git config user.name 'Peter Evans'
+          git config user.email 'peter-evans@users.noreply.github.com'
+          date +%s > report.txt
+          git commit -am "Modify tracked file during workflow"
+          date +%s > new-report.txt
+          git add -A
+          git commit -m "Add untracked file during workflow"
+      - name: Uncommitted change
+        run: date +%s > report.txt
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+```
+
+### Auto-merge
+
+Auto-merge can be enabled on a pull request allowing it to be automatically merged once requirements have been satisfied.
+See [enable-pull-request-automerge](https://github.com/peter-evans/enable-pull-request-automerge) action for usage details.
+
+## Reference Example
+
+The following workflow sets many of the action's inputs for reference purposes.
+Check the [defaults](#action-inputs) to avoid setting inputs unnecessarily.
+
+See [examples](docs/examples.md) for more realistic use cases.
+
+```yml
+jobs:
+  createPullRequest:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+
+      - name: Make changes to pull request
+        run: date +%s > report.txt
+
+      - name: Create Pull Request
+        id: cpr
+        uses: peter-evans/create-pull-request@v7
+        with:
+          token: ${{ secrets.PAT }}
+          commit-message: Update report

+          author: ${{ github.actor }} <${{ github.actor_id }}+${{ github.actor }}@users.noreply.github.com>
+          signoff: false
+          branch: example-patches
+          delete-branch: true
+          title: '[Example] Update report'
+          body: |
+            Update report
+            - Updated with *today's* date
+            - Auto-generated by [create-pull-request][1]
+
+            [1]: https://github.com/peter-evans/create-pull-request
+          labels: |

+
+## Troubleshooting
+
+### Create using an existing branch as the PR branch
+
+A common point of confusion is to try and use an existing branch containing changes to raise in a PR as the `branch` input. This will not work because the action is primarily designed to be used in workflows where the PR branch does not exist yet. The action creates and manages the PR branch itself.
+
+If you have an existing branch that you just want to create a PR for, then I recommend using the official [GitHub CLI](https://cli.github.com/manual/gh_pr_create) in a workflow step.
+
+Alternatively, if you are trying to keep a branch up to date with another branch, then you can follow [this example](https://github.com/peter-evans/create-pull-request/blob/main/docs/examples.md#keep-a-branch-up-to-date-with-another).
+
+## Frequently requested features
+
+### Disable force updates to existing PR branches
+
+This behaviour is fundamental to how the action works and is a conscious design decision. The "rule" that I based this design on is that when a workflow executes the action to create or update a PR, the result of those two possible actions should never be different. The easiest way to maintain that consistency is to rebase the PR branch and force push it.
+
+If you want to avoid this behaviour there are some things that might work depending on your use case:
+- Check if the pull request branch exists in a separate step before the action runs and act accordingly.
+- Use the [alternative strategy](https://github.com/peter-evans/create-pull-request#alternative-strategy---always-create-a-new-pull-request-branch) of always creating a new PR that won't be updated by the action.
+- [Create your own commits](https://github.com/peter-evans/create-pull-request#create-your-own-commits) each time the action is created/updated.
+
+### Add a no-verify option to bypass git hooks
+
+Presently, there is no plan to add this feature to the action.
+The reason is that I'm trying very hard to keep the interface for this action to a minimum to prevent it becoming bloated and complicated.
+
+Git hooks must be installed after a repository is checked out in order for them to work.
+So the straightforward solution is to just not install them during the workflow where this action is used.
+
+- If hooks are automatically enabled by a framework, use an option provided by the framework to disable them. For example, for Husky users, they can be disabled with the `--ignore-scripts` flag, or by setting the `HUSKY` environment variable when the action runs.
+  ```yml
+  uses: peter-evans/create-pull-request@v7
+  env:
+    HUSKY: '0'
+  ```
+- If hooks are installed in a script, then add a condition checking if the `CI` environment variable exists.
+   ```sh
+   #!/bin/sh
+
+   [ -n "$CI" ] && exit 0
+   ```
+- If preventing the hooks installing is problematic, just delete them in a workflow step before the action runs.
+   ```yml
+   - run: rm .git/hooks -rf
+   ```

+
+## Terminology
+
+[Pull requests](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests#about-pull-requests) are proposed changes to a repository branch that can be reviewed by a repository's collaborators before being accepted or rejected. 
+
+A pull request references two branches:
+
+- The `base` of a pull request is the branch you intend to change once the proposed changes are merged.
+- The `branch` of a pull request represents what you intend the `base` to look like when merged. It is the `base` branch *plus* changes that have been made to it.
+
+## Events and checkout
+
+This action expects repositories to be checked out with the official GitHub Actions [checkout](https://github.com/actions/checkout) action.
+For each [event type](https://docs.github.com/en/actions/reference/events-that-trigger-workflows) there is a default `GITHUB_SHA` that will be checked out.
+
+The default can be overridden by specifying a `ref` on checkout.
+
+```yml
+      - uses: actions/checkout@v4
+        with:
+          ref: develop
+```
+
+## How the action works
+
+Unless the `base` input is supplied, the action expects the target repository to be checked out on the pull request `base`—the branch you intend to modify with the proposed changes.
+
+Workflow steps:
+
+1. Checkout the `base` branch
+2. Make changes
+3. Execute `create-pull-request` action
+
+The following git diagram shows how the action creates and updates a pull request branch.
+
+![Create Pull Request GitGraph](assets/cpr-gitgraph.png)
+
+## Guidelines
+
+### Providing a consistent base
+
+For the action to work correctly it should be executed in a workflow that checks out a *consistent* base branch. This will be the base of the pull request unless overridden with the `base` input.
+
+This means your workflow should be consistently checking out the branch that you intend to modify once the PR is merged.
+
+In the following example, the [`push`](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#push) and [`create`](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#create) events both trigger the same workflow. This will cause the checkout action to checkout inconsistent branches and commits. Do *not* do this. It will cause multiple pull requests to be created for each additional `base` the action is executed against.
+
+```yml
+on:
+  push:
+  create:
+jobs:
+  example:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+```
+
+There may be use cases where it makes sense to execute the workflow on a branch that is not the base of the pull request. In these cases, the base branch can be specified with the `base` action input. The action will attempt to rebase changes made during the workflow on to the actual base.
+
+### Events which checkout a commit
+
+The [default checkout](#events-and-checkout) for the majority of events will leave the repository checked out on a branch.
+However, some events such as `release` and `pull_request` will leave the repository in a "detached HEAD" state.
+This is because they checkout a commit, not a branch.
+In these cases, you *must supply* the `base` input so the action can rebase changes made during the workflow for the pull request.
+
+Workflows triggered by [`pull_request`](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#pull_request) events will by default check out a merge commit. Set the `base` input as follows to base the new pull request on the current pull request's branch.
+
+```yml
+      - uses: peter-evans/create-pull-request@v7
+        with:
+          base: ${{ github.head_ref }}
+```
+
+Workflows triggered by [`release`](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#release) events will by default check out a tag. For most use cases, you will need to set the `base` input to the branch name of the tagged commit.
+
+```yml
+      - uses: peter-evans/create-pull-request@v7
+        with:
+          base: main
+```
+
+### Restrictions on repository forks
+
+GitHub Actions have imposed restrictions on workflow runs triggered by public repository forks.
+Private repositories can be configured to [enable workflows](https://docs.github.com/en/github/administering-a-repository/disabling-or-limiting-github-actions-for-a-repository#enabling-workflows-for-private-repository-forks) from forks to run without restriction.
+
+The restrictions apply to the `pull_request` event triggered by a fork opening a pull request in the upstream repository.
+
+- Events from forks cannot access secrets, except for the default `GITHUB_TOKEN`.
+    > With the exception of GITHUB_TOKEN, secrets are not passed to the runner when a workflow is triggered from a forked repository.
+
+    [GitHub Actions: Using encrypted secrets in a workflow](https://docs.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets#using-encrypted-secrets-in-a-workflow)
+
+- The `GITHUB_TOKEN` has read-only access when an event is triggered by a forked repository.
+
+   [GitHub Actions: Permissions for the GITHUB_TOKEN](https://docs.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token#permissions-for-the-github_token)
+
+These restrictions mean that during a `pull_request` event triggered by a forked repository, actions have no write access to GitHub resources and will fail on any attempt.
+
+A job condition can be added to prevent workflows from executing when triggered by a repository fork.
+
+```yml
+on: pull_request
+jobs:
+  example:
+    runs-on: ubuntu-latest
+    # Check if the event is not triggered by a fork
+    if: github.event.pull_request.head.repo.full_name == github.repository
+```
+
+For further reading regarding the security of pull requests, see this GitHub blog post titled [Keeping your GitHub Actions and workflows secure: Preventing pwn requests](https://securitylab.github.com/research/github-actions-preventing-pwn-requests/)
+
+### Triggering further workflow runs
+
+Pull requests created by the action using the default `GITHUB_TOKEN` cannot trigger other workflows. If you have `on: pull_request` or `on: push` workflows acting as checks on pull requests, they will not run.
+
+> When you use the repository's `GITHUB_TOKEN` to perform tasks, events triggered by the `GITHUB_TOKEN` will not create a new workflow run. This prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository's `GITHUB_TOKEN`, a new workflow will not run even when the repository contains a workflow configured to run when `push` events occur.
+
+[GitHub Actions: Triggering a workflow from a workflow](https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow)
+
+#### Workarounds to trigger further workflow runs
+
+There are a number of workarounds with different pros and cons.
+
+- Use the default `GITHUB_TOKEN` and allow the action to create pull requests that have no checks enabled. Manually close pull requests and immediately reopen them. This will enable `on: pull_request` workflows to run and be added as checks. To prevent merging of pull requests without checks erroneously, use [branch protection rules](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/defining-the-mergeability-of-pull-requests).
+
+- Create draft pull requests by setting the `draft: always-true` input, and configure your workflow to trigger `on: ready_for_review`. The workflow will run when users manually click the "Ready for review" button on the draft pull requests. If the pull request is updated by the action, the `always-true` mode ensures that the pull request will be converted back to a draft.
+
+- Use a [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) created on an account that has write access to the repository that pull requests are being created in. This is the standard workaround and [recommended by GitHub](https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#triggering-a-workflow-from-a-workflow). It's advisable to use a dedicated [machine account](https://docs.github.com/en/github/site-policy/github-terms-of-service#3-account-requirements) that has collaborator access to the repository, rather than creating a PAT on a personal user account. Also note that because the account that owns the PAT will be the creator of pull requests, that user account will be unable to perform actions such as request changes or approve the pull request.
+
+- Use [SSH (deploy keys)](#push-using-ssh-deploy-keys) to push the pull request branch. This is arguably more secure than using a PAT because deploy keys can be set per repository. However, this method will only trigger `on: push` workflows.
+
+- Use a [machine account that creates pull requests from its own fork](#push-pull-request-branches-to-a-fork). This is the most secure because the PAT created only grants access to the machine account's fork, not the main repository. This method will trigger `on: pull_request` workflows to run. Workflows triggered `on: push` will not run because the push event is in the fork.
+
+- Use a [GitHub App to generate a token](#authenticating-with-github-app-generated-tokens) that can be used with this action. GitHub App generated tokens are more secure than using a Classic PAT because access permissions can be set with finer granularity and are scoped to only repositories where the App is installed. This method will trigger both `on: push` and `on: pull_request` workflows.
+
+### Security
+
+From a security perspective it's good practice to fork third-party actions, review the code, and use your fork of the action in workflows.
+By using third-party actions directly the risk exists that it could be modified to do something malicious, such as capturing secrets.
+
+Alternatively, use the action directly and reference the commit hash for the version you want to target.
+```yml
+  - uses: thirdparty/foo-action@172ec762f2ac8e050062398456fccd30444f8f30
+```
+
+This action uses [ncc](https://github.com/vercel/ncc) to compile the Node.js code and dependencies into a single JavaScript file under the [dist](https://github.com/peter-evans/create-pull-request/tree/main/dist) directory.
+
+## Advanced usage
+
+### Creating pull requests in a remote repository
+
+Checking out a branch from a different repository from where the workflow is executing will make *that repository* the target for the created pull request. In this case, the `GITHUB_TOKEN` will not work and one of the other [token options](../README.md#token) must be used.
+
+```yml
+      - uses: actions/checkout@v4
+        with:
+          token: ${{ secrets.PAT }}
+          repository: owner/repo
+
+      # Make changes to pull request here
+
+      - uses: peter-evans/create-pull-request@v7
+        with:
+          token: ${{ secrets.PAT }}
+```
+
+### Push using SSH (deploy keys)
+
+[Deploy keys](https://developer.github.com/v3/guides/managing-deploy-keys/#deploy-keys) can be set per repository and so are arguably more secure than using a Classic [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token).
+Allowing the action to push with a configured deploy key will trigger `on: push` workflows. This makes it an alternative to using a PAT to trigger checks for pull requests.
+
+> [!NOTE]
+> You cannot use deploy keys alone to [create a pull request in a remote repository](#creating-pull-requests-in-a-remote-repository) because then using a PAT would become a requirement.
+> This method only makes sense if creating a pull request in the repository where the workflow is running.
+
+How to use SSH (deploy keys) with create-pull-request action:
+
+1. [Create a new SSH key pair](https://docs.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#generating-a-new-ssh-key) for your repository. Do not set a passphrase.
+2. Copy the contents of the public key (.pub file) to a new repository [deploy key](https://developer.github.com/v3/guides/managing-deploy-keys/#deploy-keys) and check the box to "Allow write access."
+3. Add a secret to the repository containing the entire contents of the private key.
+4. As shown in the example below, configure `actions/checkout` to use the deploy key you have created.
+
+```yml
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          ssh-key: ${{ secrets.SSH_PRIVATE_KEY }}
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+```
+
+### Push pull request branches to a fork
+
+Instead of pushing pull request branches to the repository you want to update, you can push them to a fork of that repository.
+This allows you to employ the [principle of least privilege](https://en.wikipedia.org/wiki/Principle_of_least_privilege) by using a dedicated user acting as a [machine account](https://docs.github.com/en/github/site-policy/github-terms-of-service#3-account-requirements).
+This user only has `read` access to the main repository.
+It will use their own fork to push code and create the pull request.
+
+> [!NOTE]
+> If you choose to not give the machine account `write` access to the parent repository, the following inputs cannot be used: `labels`, `assignees`, `reviewers`, `team-reviewers` and `milestone`.
+
+1. Create a new GitHub user and login.
+2. Fork the repository that you will be creating pull requests in.
+3. Create a Classic [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) with `repo` and `workflow` scopes.
+4. Logout and log back into your main user account.
+5. Add a secret to your repository containing the above PAT.
+6. As shown in the following example workflow, set the `push-to-fork` input to the full repository name of the fork.
+
+```yaml
+      - uses: actions/checkout@v4
+
+      # Make changes to pull request here
+
+      - uses: peter-evans/create-pull-request@v7
+        with:
+          token: ${{ secrets.MACHINE_USER_PAT }}
+          push-to-fork: machine-user/fork-of-repository
+```
+
+> [!TIP]
+> You can also combine `push-to-fork` with [creating pull requests in a remote repository](#creating-pull-requests-in-a-remote-repository).
+
+#### Pushing to a fork with fine-grained permissions
+
+Using a fine-grained [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) or [GitHub App](#authenticating-with-github-app-generated-tokens) with `push-to-fork` can be achieved, but comes with some caveats.
+
+When using `push-to-fork`, the action needs permissions for two different repositories.
+It needs `contents: write` for the fork to push the branch, and `pull-requests: write` for the parent repository to create the pull request.
+
+There are two main scenarios:
+1. The parent and fork have different owners. In this case, it's not possible to create a token that is scoped to both repositories so different tokens must be used for each.
+2. The parent and fork both have the same owner (i.e. they exist in the same org). In this case, a single token can be scoped to both repositories, but the permissions granted cannot be different. So it would defeat the purpose of using `push-to-fork`, and you might as well just create the pull request directly on the parent repository.
+
+For the first scenario, the solution is to scope the token for the fork, and use the `branch-token` input to push the branch.
+The `token` input will then default to the repository's `GITHUB_TOKEN`, which will be used to create the pull request.
+
+> [!NOTE]
+> Solution limitations:
+> - Since `GITHUB_TOKEN` will be used to create the pull request, the workflow *must* be executing in the parent repository where the pull request should be created.
+> - `maintainer-can-modify` *must* be set to `false`, because the `GITHUB_TOKEN` will not have `write` access to the head branch in the fork.
+
+The following is an example of pushing to a fork using GitHub App tokens.
+```yaml
+      - uses: actions/create-github-app-token@v1
+        id: generate-token
+        with:
+          app-id: ${{ secrets.APP_ID }}
+          private-key: ${{ secrets.APP_PRIVATE_KEY }}
+          owner: owner
+          repositories: fork-of-repo
+
+      - uses: actions/checkout@v4
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          branch-token: ${{ steps.generate-token.outputs.token }}
+          push-to-fork: owner/fork-of-repo
+          maintainer-can-modify: false
+```
+
+### Authenticating with GitHub App generated tokens
+
+A GitHub App can be created for the sole purpose of generating tokens for use with GitHub actions.
+GitHub App generated tokens can be configured with fine-grained permissions and are scoped to only repositories where the App is installed.
+
+1. Create a minimal [GitHub App](https://docs.github.com/en/developers/apps/creating-a-github-app), setting the following fields:
+
+    - Set `GitHub App name`.
+    - Set `Homepage URL` to anything you like, such as your GitHub profile page.
+    - Uncheck `Active` under `Webhook`. You do not need to enter a `Webhook URL`.
+    - Under `Repository permissions: Contents` select `Access: Read & write`.
+    - Under `Repository permissions: Pull requests` select `Access: Read & write`.
+    - Under `Repository permissions: Workflows` select `Access: Read & write`.
+      - **NOTE**: Only needed if pull requests could contain changes to Actions workflows.
+    - Under `Organization permissions: Members` select `Access: Read-only`.
+      - **NOTE**: Only needed if you would like add teams as reviewers to PRs.
+
+2. Create a Private key from the App settings page and store it securely.
+
+3. Install the App on repositories that the action will require access to in order to create pull requests.
+
+4. Set secrets on your repository containing the GitHub App ID, and the private key you created in step 2. e.g. `APP_ID`, `APP_PRIVATE_KEY`.
+
+5. The following example workflow shows how to use [actions/create-github-app-token](https://github.com/actions/create-github-app-token) to generate a token for use with this action.
+
+```yaml
+    steps:
+      - uses: actions/create-github-app-token@v1
+        id: generate-token
+        with:
+          app-id: ${{ secrets.APP_ID }}
+          private-key: ${{ secrets.APP_PRIVATE_KEY }}
+
+      - uses: actions/checkout@v4
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          token: ${{ steps.generate-token.outputs.token }}
+```
+
+#### Creating pull requests in a remote repository using GitHub App generated tokens
+
+For this case a token must be generated from the GitHub App installation of the remote repository.
+
+In the following example, a pull request is being created in remote repo `owner/repo`.
+```yaml
+    steps:
+      - uses: actions/create-github-app-token@v1
+        id: generate-token
+        with:
+          app-id: ${{ secrets.APP_ID }}
+          private-key: ${{ secrets.APP_PRIVATE_KEY }}
+          owner: owner
+          repositories: repo
+
+      - uses: actions/checkout@v4
+        with:
+          token: ${{ steps.generate-token.outputs.token }} # necessary if the repo is private
+          repository: owner/repo
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          token: ${{ steps.generate-token.outputs.token }}
+```
+
+### Commit signing
+
+[Commit signature verification](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification) is a feature where GitHub will mark signed commits as "verified" to give confidence that changes are from a trusted source.
+Some organizations require commit signing, and enforce it with branch protection rules.
+
+The action supports two methods to sign commits, [commit signature verification for bots](#commit-signature-verification-for-bots), and [GPG commit signature verification](#gpg-commit-signature-verification).
+
+#### Commit signature verification for bots
+
+The action can sign commits as `github-actions[bot]` when using the repository's default `GITHUB_TOKEN`, or your own bot when using [GitHub App tokens](#authenticating-with-github-app-generated-tokens).
+
+> [!IMPORTANT]  
+> - When setting `sign-commits: true` the action will ignore the `committer` and `author` inputs.
+> - If you attempt to use a [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) the action will create the pull request, but commits will *not* be signed. Commit signing is only supported with bot generated tokens.
+> - The GitHub API has a 40MiB limit when creating git blobs. An error will be raised if there are files in the pull request larger than this. If you hit this limit, use [GPG commit signature verification](#gpg-commit-signature-verification) instead.
+
+In this example the `token` input is not supplied, so the action will use the repository's default `GITHUB_TOKEN`. This will sign commits as `github-actions[bot]`.
+```yaml
+    steps:
+      - uses: actions/checkout@v4
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          sign-commits: true
+```
+
+In this example, the `token` input is generated using a GitHub App. This will sign commits as `<application-name>[bot]`.
+```yaml
+    steps:
+      - uses: actions/checkout@v4
+
+      - uses: actions/create-github-app-token@v1
+        id: generate-token
+        with:
+          app-id: ${{ secrets.APP_ID }}
+          private-key: ${{ secrets.APP_PRIVATE_KEY }}
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          token: ${{ steps.generate-token.outputs.token }}
+          sign-commits: true
+```
+
+#### GPG commit signature verification
+
+The action can use GPG to sign commits with a GPG key that you generate yourself.
+
+1. Follow GitHub's guide to [generate a new GPG key](https://docs.github.com/en/github/authenticating-to-github/generating-a-new-gpg-key).
+
+2. [Add the public key](https://docs.github.com/en/github/authenticating-to-github/adding-a-new-gpg-key-to-your-github-account) to the user account associated with the [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) that you will use with the action.
+
+3. Copy the private key to your clipboard, replacing `email@example.com` with the email address of your GPG key.
+   ```
+   # macOS
+   gpg --armor --export-secret-key email@example.com | pbcopy
+   ```
+
+4. Paste the private key into a repository secret where the workflow will run. e.g. `GPG_PRIVATE_KEY`
+
+5. Create another repository secret for the key's passphrase, if applicable. e.g. `GPG_PASSPHRASE`
+
+6. The following example workflow shows how to use [crazy-max/ghaction-import-gpg](https://github.com/crazy-max/ghaction-import-gpg) to import your GPG key and allow the action to sign commits.
+
+> [!IMPORTANT]
+> The `committer` email address *MUST* match the email address used to create your GPG key.
+
+```yaml
+    steps:
+      - uses: actions/checkout@v4
+
+      - uses: crazy-max/ghaction-import-gpg@v5
+        with:
+          gpg_private_key: ${{ secrets.GPG_PRIVATE_KEY }}
+          passphrase: ${{ secrets.GPG_PASSPHRASE }}
+          git_user_signingkey: true
+          git_commit_gpgsign: true
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          token: ${{ secrets.PAT }}
+          committer: example <email@example.com>
+```
+
+### Running in a container or on self-hosted runners
+
+This action can be run inside a container, or on [self-hosted runners](https://docs.github.com/en/actions/hosting-your-own-runners), by installing the necessary dependencies.
+
+This action requires `git` to be installed and on the `PATH`. Note that `actions/checkout` requires Git 2.18 or higher to be installed, otherwise it will just download the source of the repository instead of cloning it.
+
+The following examples of running in a container show the dependencies being installed during the workflow, but they could also be pre-installed in a custom image.
+
+**Alpine container example:**
+```yml
+jobs:
+  createPullRequestAlpine:
+    runs-on: ubuntu-latest
+    container:
+      image: alpine
+    steps:
+      - name: Install dependencies
+        run: apk --no-cache add git
+
+      - uses: actions/checkout@v4
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+```
+
+**Ubuntu container example:**
+```yml
+jobs:
+  createPullRequestAlpine:
+    runs-on: ubuntu-latest
+    container:
+      image: ubuntu
+    steps:
+      - name: Install dependencies
+        run: |
+          apt-get update
+          apt-get install -y software-properties-common
+          add-apt-repository -y ppa:git-core/ppa
+          apt-get install -y git
+
+      - uses: actions/checkout@v4
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+```

+
+
+## Use case: Create a pull request to update X on push
+
+This pattern will work well for updating any kind of static content based on pushed changes. Care should be taken when using this pattern in repositories with a high frequency of commits.
+
+### Update project authors
+
+Raises a pull request to update a file called `AUTHORS` with the git user names and email addresses of contributors.
+
+```yml
+name: Update AUTHORS
+on:
+  push:
+    branches:
+      - main
+jobs:
+  updateAuthors:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          fetch-depth: 0
+      - name: Update AUTHORS
+        run: |
+          git log --format='%aN <%aE>%n%cN <%cE>' | sort -u > AUTHORS
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          commit-message: update authors
+          title: Update AUTHORS
+          body: Credit new contributors by updating AUTHORS
+          branch: update-authors
+```
+
+### Keep a branch up-to-date with another
+
+This is a use case where a branch should be kept up to date with another by opening a pull request to update it. The pull request should then be updated with new changes until it is merged or closed.
+
+In this example scenario, a branch called `production` should be updated via pull request to keep it in sync with `main`. Merging the pull request is effectively promoting those changes to production.
+
+```yml
+name: Create production promotion pull request
+on:
+  push:
+    branches:
+      - main
+jobs:
+  productionPromotion:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          ref: production
+      - name: Reset promotion branch
+        run: |
+          git fetch origin main:main
+          git reset --hard main
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          branch: production-promotion
+```
+
+## Use case: Create a pull request to update X on release
+
+This pattern will work well for updating any kind of static content based on the tagged commit of a release. Note that because `release` is one of the [events which checkout a commit](concepts-guidelines.md#events-which-checkout-a-commit) it is necessary to supply the `base` input to the action.
+
+### Update changelog
+
+Raises a pull request to update the `CHANGELOG.md` file based on the tagged commit of the release.
+Note that [git-chglog](https://github.com/git-chglog/git-chglog/) requires some configuration files to exist in the repository before this workflow will work.
+
+This workflow assumes the tagged release was made on a default branch called `main`.
+
+```yml
+name: Update Changelog
+on:
+  release:
+    types: [published]
+jobs:
+  updateChangelog:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          fetch-depth: 0
+      - name: Update Changelog
+        run: |
+          curl -o git-chglog -L https://github.com/git-chglog/git-chglog/releases/download/0.9.1/git-chglog_linux_amd64
+          chmod u+x git-chglog
+          ./git-chglog -o CHANGELOG.md
+          rm git-chglog
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          commit-message: update changelog
+          title: Update Changelog
+          body: Update changelog to reflect release changes
+          branch: update-changelog
+          base: main
+```
+
+## Use case: Create a pull request to update X periodically
+
+This pattern will work well for updating any kind of static content from an external source. The workflow executes on a schedule and raises a pull request when there are changes.
+
+### Update NPM dependencies
+
+This workflow will create a pull request for npm dependencies.
+It works best in combination with a build workflow triggered on `push` and `pull_request`.
+A [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) can be used in order for the creation of the pull request to trigger further workflows. See the [documentation here](concepts-guidelines.md#triggering-further-workflow-runs) for further details.
+
+```yml
+name: Update Dependencies
+on:
+  schedule:
+    - cron:  '0 10 * * 1'
+jobs:
+  update-dep:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v3
+        with:
+          node-version: '16.x'
+      - name: Update dependencies
+        run: |
+          npx -p npm-check-updates ncu -u
+          npm install
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+            token: ${{ secrets.PAT }}
+            commit-message: Update dependencies
+            title: Update dependencies
+            body: |
+              - Dependency updates
+  
+              Auto-generated by [create-pull-request][1]
+  
+              [1]: https://github.com/peter-evans/create-pull-request
+            branch: update-dependencies
+```
+
+The above workflow works best in combination with a build workflow triggered on `push` and `pull_request`.
+
+```yml
+name: CI
+on:
+  push:
+    branches: [main]
+  pull_request:
+    branches: [main]
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-node@v3
+        with:
+          node-version: 16.x
+      - run: npm ci
+      - run: npm run test
+      - run: npm run build
+```
+
+### Update Gradle dependencies
+
+The following workflow will create a pull request for Gradle dependencies.
+It requires first configuring your project to use Gradle lockfiles.
+See [here](https://github.com/peter-evans/gradle-auto-dependency-updates) for how to configure your project and use the following workflow.
+
+```yml
+name: Update Dependencies
+on:
+  schedule:
+    - cron:  '0 1 * * 1'
+jobs:
+  update-dep:

+### Update Cargo dependencies
+
+The following workflow will create a pull request for Cargo dependencies.
+It optionally uses [`cargo-edit`](https://github.com/killercup/cargo-edit) to update `Cargo.toml` and keep it in sync with `Cargo.lock`.
+
+```yml

+
+### Update SwaggerUI for GitHub Pages
+
+When using [GitHub Pages to host Swagger documentation](https://github.com/peter-evans/swagger-github-pages), this workflow updates the repository with the latest distribution of [SwaggerUI](https://github.com/swagger-api/swagger-ui).
+
+You must create a file called `swagger-ui.version` at the root of your repository before running.
+```yml
+name: Update Swagger UI
+on:
+  schedule:
+    - cron:  '0 10 * * *'
+jobs:

+          echo "release_tag=$release_tag" >> $GITHUB_OUTPUT
+          current_tag=$(<swagger-ui.version)

+        with:
+          commit-message: Update swagger-ui to ${{ steps.swagger-ui.outputs.release_tag }}

+          branch: swagger-ui-updates
+```
+
+### Keep a fork up-to-date with its upstream
+
+This example is designed to be run in a separate repository from the fork repository itself.
+The aim of this is to prevent committing anything to the fork's default branch would cause it to differ from the upstream.
+
+In the following example workflow, `owner/repo` is the upstream repository and `fork-owner/repo` is the fork. It assumes the default branch of the upstream repository is called `main`.
+
+The [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) should have `repo` scope. Additionally, if the upstream makes changes to the `.github/workflows` directory, the action will be unable to push the changes to a branch and throw the error "_(refusing to allow a GitHub App to create or update workflow `.github/workflows/xxx.yml` without `workflows` permission)_". To allow these changes to be pushed to the fork, add the `workflow` scope to the PAT. Of course, allowing this comes with the risk that the workflow changes from the upstream could run and do something unexpected. Disabling GitHub Actions in the fork is highly recommended to prevent this.
+
+When you merge the pull request make sure to choose the [`Rebase and merge`](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-request-merges#rebase-and-merge-your-pull-request-commits) option. This will make the fork's commits match the commits on the upstream.
+
+```yml
+name: Update fork
+on:
+  schedule:
+    - cron:  '0 0 * * 0'
+jobs:
+  updateFork:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          repository: fork-owner/repo
+      - name: Reset the default branch with upstream changes
+        run: |
+          git remote add upstream https://github.com/owner/repo.git
+          git fetch upstream main:upstream-main
+          git reset --hard upstream-main
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          token: ${{ secrets.PAT }}
+          branch: upstream-changes
+```
+
+### Spider and download a website
+
+This workflow spiders a website and downloads the content. Any changes to the website will be raised in a pull request.
+
+```yml
+name: Download Website
+on:
+  schedule:
+    - cron:  '0 10 * * *'
+jobs:
+  format:
+    runs-on: ubuntu-latest
+    steps:

+          title: Automated Updates to Local Website Copy
+          body: This is an auto-generated PR with website updates.
+          branch: website-updates
+```
+
+## Use case: Create a pull request to update X by calling the GitHub API
+
+You can use the GitHub API to trigger a webhook event called [`repository_dispatch`](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#repository_dispatch) when you want to trigger a workflow for any activity that happens outside of GitHub.
+This pattern will work well for updating any kind of static content from an external source.
+
+You can modify any of the examples in the previous section to work in this fashion.
+
+Set the workflow to execute `on: repository_dispatch`.
+
+```yml
+on:
+  repository_dispatch:
+    types: [create-pull-request]
+```
+
+### Call the GitHub API from an external service
+
+An `on: repository_dispatch` workflow can be triggered by a call to the GitHub API as follows.
+
+- `[username]` is a GitHub username
+- `[token]` is a `repo` scoped [Personal Access Token](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token)
+- `[repository]` is the name of the repository the workflow resides in.
+
+```
+curl -XPOST -u "[username]:[token]" \
+  -H "Accept: application/vnd.github.everest-preview+json" \
+  -H "Content-Type: application/json" \
+  https://api.github.com/repos/[username]/[repository]/dispatches \
+  --data '{"event_type": "create-pull-request"}'
+```
+
+### Call the GitHub API from another GitHub Actions workflow
+
+An `on: repository_dispatch` workflow can be triggered from another workflow with [repository-dispatch](https://github.com/peter-evans/repository-dispatch) action.
+
+```yml
+- name: Repository Dispatch
+  uses: peter-evans/repository-dispatch@v2
+  with:
+    token: ${{ secrets.REPO_ACCESS_TOKEN }}
+    repository: username/my-repo
+    event-type: create-pull-request
+    client-payload: '{"ref": "${{ github.ref }}", "sha": "${{ github.sha }}"}'
+```
+
+## Use case: Create a pull request to modify/fix pull requests
+
+**Note**: While the following approach does work, my strong recommendation would be to use a slash command style "ChatOps" solution for operations on pull requests. See [slash-command-dispatch](https://github.com/peter-evans/slash-command-dispatch) for such a solution.
+
+This is a pattern that lends itself to automated code linting and fixing. A pull request can be created to fix or modify something during an `on: pull_request` workflow. The pull request containing the fix will be raised with the original pull request as the base. This can be then be merged to update the original pull request and pass any required tests.
+
+Note that due to [token restrictions on public repository forks](https://docs.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token#permissions-for-the-github_token), workflows for this use case do not work for pull requests raised from forks.
+Private repositories can be configured to [enable workflows](https://docs.github.com/en/github/administering-a-repository/disabling-or-limiting-github-actions-for-a-repository#enabling-workflows-for-private-repository-forks) from forks to run without restriction. 
+
+### autopep8
+
+The following is an example workflow for a use case where [autopep8 action](https://github.com/peter-evans/autopep8) runs as both a check on pull requests and raises a further pull request to apply code fixes.
+
+How it works:
+
+1. When a pull request is raised the workflow executes as a check
+2. If autopep8 makes any fixes a pull request will be raised for those fixes to be merged into the current pull request branch. The workflow then deliberately causes the check to fail.
+3. When the pull request containing the fixes is merged the workflow runs again. This time autopep8 makes no changes and the check passes.
+4. The original pull request can now be merged.
+
+```yml
+name: autopep8
+on: pull_request
+jobs:
+  autopep8:
+    # Check if the PR is not raised by this workflow and is not from a fork
+    if: startsWith(github.head_ref, 'autopep8-patches') == false && github.event.pull_request.head.repo.full_name == github.repository
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          ref: ${{ github.head_ref }}
+      - name: autopep8
+        id: autopep8
+        uses: peter-evans/autopep8@v1
+        with:
+          args: --exit-code --recursive --in-place --aggressive --aggressive .
+      - name: Set autopep8 branch name
+        id: vars
+        run: |
+          branch-name="autopep8-patches/${{ github.head_ref }}"
+          echo "branch-name=$branch-name" >> $GITHUB_OUTPUT
+      - name: Create Pull Request
+        if: steps.autopep8.outputs.exit-code == 2
+        uses: peter-evans/create-pull-request@v7
+        with:
+          commit-message: autopep8 action fixes
+          title: Fixes by autopep8 action
+          body: This is an auto-generated PR with fixes by autopep8.
+          labels: autopep8, automated pr
+          branch: ${{ steps.vars.outputs.branch-name }}
+      - name: Fail if autopep8 made changes
+        if: steps.autopep8.outputs.exit-code == 2
+        run: exit 1
+```
+
+## Misc workflow tips
+
+### Filtering push events
+
+For workflows using `on: push` you may want to ignore push events for tags and only execute for branches. Specifying `branches` causes only events on branches to trigger the workflow. The `'**'` wildcard will match any branch name.
+
+```yml
+on:
+  push:
+    branches:
+      - '**' 
+```
+
+If you have a workflow that contains jobs to handle push events on branches as well as tags, you can make sure that the job where you use `create-pull-request` action only executes when `github.ref` is a branch by using an `if` condition as follows.
+
+```yml
+on: push
+jobs:
+  createPullRequest:
+    if: startsWith(github.ref, 'refs/heads/')
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      ...
+
+  someOtherJob:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      ...
+```
+
+### Dynamic configuration using variables
+
+The following examples show how configuration for the action can be dynamically defined in a previous workflow step.
+Note that the step where output variables are defined must have an id.
+
+```yml
+      - name: Set output variables
+        id: vars
+        run: |
+          pr_title="[Test] Add report file $(date +%d-%m-%Y)"
+          pr_body="This PR was auto-generated on $(date +%d-%m-%Y) \
+            by [create-pull-request](https://github.com/peter-evans/create-pull-request)."
+          echo "pr_title=$pr_title" >> $GITHUB_OUTPUT
+          echo "pr_body=$pr_body" >> $GITHUB_OUTPUT
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          title: ${{ steps.vars.outputs.pr_title }}
+          body: ${{ steps.vars.outputs.pr_body }}
+```
+
+### Using a markdown template
+
+In this example, a markdown template file is added to the repository at `.github/pull-request-template.md` with the following content.
+```
+This is a test pull request template
+Render template variables such as {{ .foo }} and {{ .bar }}.
+```
+
+The template is rendered using the [render-template](https://github.com/chuhlomin/render-template) action and the result is used to create the pull request.
+```yml
+      - name: Render template
+        id: template
+        uses: chuhlomin/render-template@v1.4
+        with:
+          template: .github/pull-request-template.md
+          vars: |
+            foo: this
+            bar: that
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v7
+        with:
+          body: ${{ steps.template.outputs.result }}
+```
+
+### Debugging GitHub Actions
+
+#### Runner Diagnostic Logging
+
+[Runner diagnostic logging](https://docs.github.com/en/actions/configuring-and-managing-workflows/managing-a-workflow-run#enabling-runner-diagnostic-logging) provides additional log files that contain information about how a runner is executing an action.
+To enable runner diagnostic logging, set the secret `ACTIONS_RUNNER_DEBUG` to `true` in the repository that contains the workflow.
+
+#### Step Debug Logging
+
+[Step debug logging](https://docs.github.com/en/actions/configuring-and-managing-workflows/managing-a-workflow-run#enabling-step-debug-logging) increases the verbosity of a job's logs during and after a job's execution.
+To enable step debug logging set the secret `ACTIONS_STEP_DEBUG` to `true` in the repository that contains the workflow.
+
+#### Output Various Contexts
+
+```yml
+    steps:
+      - name: Dump GitHub context
+        env:
+          GITHUB_CONTEXT: ${{ toJson(github) }}
+        run: echo "$GITHUB_CONTEXT"

+## Updating from `v6` to `v7`
+
+### Behaviour changes
+
+- Action input `git-token` has been renamed `branch-token`, to be more clear about its purpose. The `branch-token` is the token that the action will use to create and update the branch.
+- The action now handles requests that have been rate-limited by GitHub. Requests hitting a primary rate limit will retry twice, for a total of three attempts. Requests hitting a secondary rate limit will not be retried.
+- The `pull-request-operation` output now returns `none` when no operation was executed.
+- Removed deprecated output environment variable `PULL_REQUEST_NUMBER`. Please use the `pull-request-number` action output instead.
+
+### What's new
+
+- The action can now sign commits as `github-actions[bot]` when using `GITHUB_TOKEN`, or your own bot when using [GitHub App tokens](concepts-guidelines.md#authenticating-with-github-app-generated-tokens). See [commit signing](concepts-guidelines.md#commit-signature-verification-for-bots) for details.
+- Action input `draft` now accepts a new value `always-true`. This will set the pull request to draft status when the pull request is updated, as well as on creation.
+- A new action input `maintainer-can-modify` indicates whether [maintainers can modify](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/allowing-changes-to-a-pull-request-branch-created-from-a-fork) the pull request. The default is `true`, which retains the existing behaviour of the action.
+- A new output `pull-request-commits-verified` returns `true` or `false`, indicating whether GitHub considers the signature of the branch's commits to be verified.
+
+## Updating from `v5` to `v6`
+
+### Behaviour changes
+
+- The default values for `author` and `committer` have changed. See "What's new" below for details. If you are overriding the default values you will not be affected by this change.
+- On completion, the action now removes the temporary git remote configuration it adds when using `push-to-fork`. This should not affect you unless you were using the temporary configuration for some other purpose after the action completes.
+
+### What's new
+
+- Updated runtime to Node.js 20
+  - The action now requires a minimum version of [v2.308.0](https://github.com/actions/runner/releases/tag/v2.308.0) for the Actions runner. Update self-hosted runners to v2.308.0 or later to ensure compatibility.
+- The default value for `author` has been changed to `${{ github.actor }} <${{ github.actor_id }}+${{ github.actor }}@users.noreply.github.com>`. The change adds the `${{ github.actor_id }}+` prefix to the email address to align with GitHub's standard format for the author email address.
+- The default value for `committer` has been changed to `github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>`. This is to align with the default GitHub Actions bot user account.
+- Adds input `git-token`, the [Personal Access Token (PAT)](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) that the action will use for git operations. This input defaults to the value of `token`. Use this input if you would like the action to use a different token for git operations than the one used for the GitHub API.
+- `push-to-fork` now supports pushing to sibling repositories in the same network.
+- Previously, when using `push-to-fork`, the action did not remove temporary git remote configuration it adds during execution. This has been fixed and the configuration is now removed when the action completes.
+- If the pull request body is truncated due to exceeding the maximum length, the action will now suffix the body with the message "...*[Pull request body truncated]*" to indicate that the body has been truncated.
+- The action now uses `--unshallow` only when necessary, rather than as a default argument of `git fetch`. This should improve performance, particularly for large git repositories with extensive commit history.
+- The action can now be executed on one GitHub server and create pull requests on a *different* GitHub server. Server products include GitHub hosted (github.com), GitHub Enterprise Server (GHES), and GitHub Enterprise Cloud (GHEC). For example, the action can be executed on GitHub hosted and create pull requests on a GHES or GHEC instance.
+
+## Updating from `v4` to `v5`
+
+### Behaviour changes
+
+- The action will no longer leave the local repository checked out on the pull request `branch`. Instead, it will leave the repository checked out on the branch or commit that it was when the action started.
+- When using `add-paths`, uncommitted changes will no longer be destroyed. They will be stashed and restored at the end of the action run.
+
+### What's new
+
+- Adds input `body-path`, the path to a file containing the pull request body.
+- At the end of the action run the local repository is now checked out on the branch or commit that it was when the action started.
+- Any uncommitted tracked or untracked changes are now stashed and restored at the end of the action run. Currently, this can only occur when using the `add-paths` input, which allows for changes to not be committed. Previously, any uncommitted changes would be destroyed.
+- The proxy implementation has been revised but is not expected to have any change in behaviour. It continues to support the standard environment variables `http_proxy`, `https_proxy` and `no_proxy`.
+- Now sets the git `safe.directory` configuration for the local repository path. The configuration is removed when the action completes. Fixes issue https://github.com/peter-evans/create-pull-request/issues/1170.
+- Now determines the git directory path using the `git rev-parse --git-dir` command. This allows users with custom repository configurations to use the action.
+- Improved handling of the `team-reviewers` input and associated errors.
+
+## Updating from `v3` to `v4`
+
+### Behaviour changes
+
+- The `add-paths` input no longer accepts `-A` as a valid value. When committing all new and modified files the `add-paths` input should be omitted.
+
+- If using self-hosted runners or GitHub Enterprise Server, there are minimum requirements for `v4` to run. See "What's new" below for details.
+
+### What's new
+
+- Updated runtime to Node.js 16
+  - The action now requires a minimum version of v2.285.0 for the [Actions Runner](https://github.com/actions/runner/releases/tag/v2.285.0).
+  - If using GitHub Enterprise Server, the action requires [GHES 3.4](https://docs.github.com/en/enterprise-server@3.4/admin/release-notes) or later.
+
+## Updating from `v2` to `v3`
+
+### Behaviour changes
+
+- The `author` input now defaults to the user who triggered the workflow run. This default is set via [action.yml](../action.yml) as `${{ github.actor }} <${{ github.actor }}@users.noreply.github.com>`, where `github.actor` is the GitHub user account associated with the run. For example, `peter-evans <peter-evans@users.noreply.github.com>`.
+
+  To continue to use the `v2` default, set the `author` input as follows.
+  ```yaml
+      - uses: peter-evans/create-pull-request@v3
+        with:
+          author: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>
+  ```
+
+- The `author` and `committer` inputs are no longer cross-used if only one is supplied. Additionally, when neither input is set, the `author` and `committer` are no longer determined from an existing identity set in git config. In both cases, the inputs will fall back to their default set in [action.yml](../action.yml).
+
+- Deprecated inputs `project` and `project-column` have been removed in favour of an additional action step. See [Create a project card](https://github.com/peter-evans/create-pull-request#create-a-project-card) for details.
+
+- Deprecated output `pr_number` has been removed in favour of `pull-request-number`.
+
+- Input `request-to-parent` has been removed in favour of `push-to-fork`. This greatly simplifies pushing the pull request branch to a fork of the parent repository. See [Push pull request branches to a fork](concepts-guidelines.md#push-pull-request-branches-to-a-fork) for details.
+
+  e.g.
+  ```yaml
+      - uses: actions/checkout@v2
+
+      # Make changes to pull request here
+
+      - uses: peter-evans/create-pull-request@v3
+        with:
+          token: ${{ secrets.MACHINE_USER_PAT }}
+          push-to-fork: machine-user/fork-of-repository
+  ```
+
+### What's new
+
+- The action has been converted to Typescript giving it a significant performance improvement.
+
+- If you run this action in a container, or on [self-hosted runners](https://docs.github.com/en/actions/hosting-your-own-runners), `python` and `pip` are no longer required dependencies. See [Running in a container or on self-hosted runners](concepts-guidelines.md#running-in-a-container-or-on-self-hosted-runners) for details.
+
+- Inputs `labels`, `assignees`, `reviewers` and `team-reviewers` can now be newline separated, or comma separated.
+  e.g.
+  ```yml
+          labels: |
+            chore
+            dependencies
+            automated
+  ```
+
+## Updating from `v1` to `v2`
+
+### Behaviour changes
+
+- `v2` now expects repositories to be checked out with `actions/checkout@v2`
+
+  To use `actions/checkout@v1` the following step to checkout the branch is necessary.
+  ```yml
+      - uses: actions/checkout@v1
+      - name: Checkout branch
+        run: git checkout "${GITHUB_REF:11}"
+  ```
+
+- The two branch naming strategies have been swapped. Fixed-branch naming strategy is now the default. i.e. `branch-suffix: none` is now the default and should be removed from configuration if set.
+
+- `author-name`, `author-email`, `committer-name`, `committer-email` have been removed in favour of `author` and `committer`.
+  They can both be set in the format `Display Name <email@address.com>`
+
+  If neither `author` or `committer` are set the action will default to making commits as the GitHub Actions bot user.
+
+### What's new
+
+- Unpushed commits made during the workflow before the action runs will now be considered as changes to be raised in the pull request. See [Create your own commits](https://github.com/peter-evans/create-pull-request#create-your-own-commits) for details.
+- New commits made to the pull request base will now be taken into account when pull requests are updated.
+- If an updated pull request no longer differs from its base it will automatically be closed and the pull request branch deleted.
