+## Game Launching
+
+Included in this image are tools for managing [Proton versions](https://davidotek.github.io/protonup-qt/) and a [command line launcher](https://github.com/Open-Wine-Components/umu-launcher). This means once a game or application is installed via Steam it can be directly launched on init by creating a config file and modifying `/config/.config/labwc/autostart` to run `umu-run` instead of Steam.: 
+
+```
+umu-run --config /config/game.toml
+```
+
+```toml
+[umu]
+prefix = "/config/game"
+exe = "/config/Desktop/game/game.exe"
+proton = "/config/.local/share/Steam/compatibilitytools.d/GE-Proton-version"
+game_id = "0"
+```
+
+This facilitates custom home directories with pre-configured runtimes and gamefiles for baking images outside of using the Steam launcher.
