+Auto-mod installation set to ON.
+
+READ THIS FIRST:
+With this setting on, DZGUI will attempt to download and prepare mods using Valve's steamcmd tool.
+
+The first time this process is run, DZGUI will ask you to select a terminal emulator of your preference to spawn the installation routine. If you don't have a preference or don't know, you can pick any.
+
+Installation will kick off in a separate window and may ask you for input such as your sudo password in order to install system packages and create the steamcmd user.
+
+steamcmd itself will ask for your Steam credentials. This information is used directly by Valve's steamcmd tool to authenticate your account and let you download mods headlessly. steamcmd is an official program created by Valve and communicates only with their servers.
+
+NOTE: it can take some time for large mods to download, and steamcmd will not inform you of activity until each one is finished downloading.
+
+If your distribution is unsupported, you don't have enough disk space to stage all of the mods, or there are other problems, DZGUI will warn you and write a report to $HOME/.local/share/dzgui/helpers/SCMD.log. You can attach this file to a bug report.
