Mod packs are third-party packages that add additional functionality to servers. If you want to run a mod pack on your server, you can use the mod pack installer on the Mod Packs page.
The mod pack list is prepopulated with mod packs added by admins.
To install the mod pack, select it from the Mod Pack dropdown, click Install and follow the instructions to finish installing the mod pack.
In case you can’t find the mod pack you are looking for, you can add a custom mod pack to the list by uploading it as a .zip file to the home directory of your server using the file manager or FTP. After you have uploaded the file, it will appear in the Mod Pack dropdown.
