 #### Notes
 * Requires [Neovim nightly](https://github.com/neovim/neovim/releases/tag/nightly) (0.5)
-* Windows is partially supported
-    * Can update Rich Presence as expected
-    * Does not yet properly handle multiple running nvim instances
+* Windows is [partially supported](https://github.com/andweeb/presence.nvim/projects/1#card-60537963), WSL is [not yet supported](https://github.com/andweeb/presence.nvim/projects/1#card-60537961)
 
 ## Configuration
-Rich Presence works right out of the box after installation by default, so configuration is optional. For those that do want to override default behaviors, however, configuration options are available in both Lua and VimL.

-## Contributing
-Pull requests are very welcome, feel free to open an issue! Here some open todo items:
-- [x] Manage workspace state across multiple nvim instances (e.g. tmux)
-- [x] Set activity on other autocommands (`TextChanged`, `VimLeavePre`)
-- [x] Use named pipes to support Windows
-- [ ] Set idle activity (track using `CursorMoved`)
-- [ ] Expose file assets table as a configurable option
-- [ ] Fix peer-to-peer nvim instance communication in Windows
-- [ ] Manage activity properly in buffers in windows and tabs
-- [ ] Retry connection after initial setup or a closed pipe (i.e. after quitting Discord app)
-- [ ] Attempt to connect to a range of pipes from `discord-ipc-0` to `discord-ipc-9` (see [note](https://github.com/discord/discord-rpc/blob/master/documentation/hard-mode.md#notes))
+## Troubleshooting
+* Ensure that Discord is running
+* Ensure that your Neovim version is on v0.5
+* Ensure Game Activity is enabled in your Discord settings
+* Enable logging and inspect the logs after opening a buffer
+    * Set the `log_level` setup option or `g:presence_log_level` to `"debug"`
+    * Load a file and see the logs with `:messages`
+* If there is a `Failed to get Discord IPC socket` error, your particular OS may not yet be supported
+    * Create a [new issue](https://github.com/andweeb/presence.nvim/issues/new) if one does not exist for your OS yet
