Modpacks published on CurseForge or Modrinth install from **Package Manager** in a few clicks. For a private or self-made pack, set the server up by hand.

## 1. Install the loader

Find out which loader and version the pack uses (for example NeoForge 21.1 for Minecraft 1.21.1). In **Package Manager**, install that loader at that version. Restart once and stop again, so it creates its folders.

## 2. Upload the mods and configs

1. In **Console**, make sure the server is stopped.
2. In **Files**, upload the pack's `mods` folder, and its `config` folder (plus `kubejs` or `defaultconfigs` if it has them).
3. To upload faster, zip them on your computer, upload the `.zip`, and use **Extract here**.

> [!WARNING]
> Leave out **client-only mods**: minimaps, shaders, HUD and sound mods. They crash servers. A pack's server files usually list which mods to remove.

## 3. Start it

Click **Start** and watch **Console**. If it stops with an error naming a mod, that mod is usually client-only or missing a dependency.

## Prefer published packs

If you can publish your pack on Modrinth or CurseForge (even unlisted), **Package Manager** can install and update it for you, and your players can install it in one click.
