Download Allium.
Allium uses Prism Launcher exclusively.
We use Prism instead of CurseForge or Modrinth because it's lightweight and open source. This enables us to circumvent licensing issues and maximize performance on low-end systems. Prism will also automatically update the pack whenever you open it.
Install Prism Launcher
Open the official Prism Launcher website. Download Prism for your computer, install it normally, and open it.
Import Allium
In Prism, select Add Instance in the top-left corner. Select Import, then paste this URL into the text box:
Open Allium
Once the import finishes processing, double-click the new Allium instance to launch it. The modpack will install itself automatically. You will be asked whether to keep Distant Horizons enabled; leave it checked unless you need to reduce memory usage. After installation completes, Minecraft will open automatically. From then on, simply open Prism and double-click the Allium instance to play.
