Installation

Installing the pack is pretty easy to do - you'll need to enter desktop mode, open up the software center, install Prism Launcher, and then add it as a non-Steam game. After that, download the modpack.

Prism Launcher

Prism Launcher is a third-party FOSS Minecraft launcher that makes it significantly easier to manage mods and modpacks. Instructions to install Prism on the Steam Deck:

2. In the bottom panel, look for the 👜 "Discover" app.
3. Press the search bar in Discover, and then press X to open the keyboard.
4. Search for "Prism Launcher," and then tap install.
5. Launch it. When it asks you for the amount of RAM, set the maximum to 6144 MB. Connect your account, and once it's complete, close the launcher.
6. Tap the Steam Deck icon in the bottom panel, and then look for "Prism Launcher." After that, right click Prism, and "Add to Steam."
7. Now, go back to Gaming Mode by double tapping the file on the desktop.

Prism is now installed. Now, we will install the pack.
