1. Download from [Modrinth](https://modrinth.com/) — match your Minecraft version
2. Upload `.jar` files to `mods/`
3. Most also require **Fabric API** installed
4. Restart

Recommended Stack [#recommended-stack]

For the best Fabric server performance, install all of:

* Lithium + FerriteCore + Krypton + C2ME

These mods don't conflict and stack their optimizations.

> 💡 **Tip:** Unlike Forge, Fabric performance mods are extremely lightweight and rarely cause compatibility issues. Install them all.
