+## Using r2modman in Steam Deck's Game Mode
+**r2modman will not work in Steam Deck's Game Mode by default.** Steam will not run .appimage files by default and will require 3rd party software in order to allow this. The following instructions will walk you through the process.
+
+1. Download AppImageLauncher from [here](https://github.com/TheAssassin/AppImageLauncher/releases/download/v2.2.0/appimagelauncher-lite-2.2.0-travis995-0f91801-x86_64.AppImage) onto your Steam Deck.
+
+2. Move the `.AppImage` file you just downloaded to your `Home` folder on your Steam Deck. (This is optional but will make the next step easier.)

+
+3. Copy and paste or enter the following into your Steam Deck's **Konsole**:
+
+```
+chmod +x appimagelauncher-lite-2.2.0-travis995-0f91801-x86_64.AppImage
+./appimagelauncher-lite-2.2.0-travis995-0f91801-x86_64.AppImage install
+```

+
+If you didn't put the AppImage file into your home folder, you'll have to enter it's directory after the `./` above.
+
+Press `Enter` on your Steam Deck's on-screen keyboard to execute the command.
+
+4. Visit the [**r2modman GitHub releases page**](https://github.com/ebkr/r2modmanPlus/releases/latest/) and download the `.AppImage` file on the lastest release.

+## Loading Default Mods in Steam Deck's Game Mode 
+If you prefer to load r2modman from desktop mode or wish to run default mods without loading r2modman, right-click the game in Steam and click `Properties`. From there, paste the following into **Launch Options**:
 
 ```
 WINEDLLOVERRIDES="winhttp=n,b" %command% --doorstop-enable true --doorstop-target "/home/deck/.config/r2modmanPlus-local/LethalCompany/profiles/Default/BepInEx/core/BepInEx.Preloader.dll" --r2profile "Default"
 ```

 This will instruct the game to launch with the Default profile we configured in r2modman earlier, so all your mods installed there will be available.
