# How to Install Modpacks on Your Minecraft Server

Install modpacks to add hundreds of mods working together on your server.

## Automatic Installation

1. Go to the **Modpacks** tab
2. Search for the modpack you want
3. Click **Install** next to your chosen modpack
4. The modpack will install automatically with the correct Forge version

## Manual Installation

If your modpack isn't in the automatic installer:

1. **Upload the modpack:**
   * Download the server archive (`.zip`) from [Modrinth](https://modrinth.com) or [CurseForge](https://curseforge.com)
   * [Upload it](/panel/importing-files) to your file manager

2. **Install Forge:**
   * Find the required Forge version in the modpack's readme (e.g., `43.2.14`)
   * Go to **Startup** tab and enter the version (e.g., `1.19.1-43.2.14`)
   * Delete all files **except** the modpack archive
   * Go to **Settings** tab and click **Reinstall**

3. **Unpack the modpack:**
   * Start the server once to generate files
   * Click the three dots next to the archive and click **Unarchive**
   * Start the server again

<Note>First startup with a modpack can take longer than usual.</Note>

## FAQ

  4. Click **Unarchive** to extract files to the main folder
