Hello ! Today we'll see how to automatically install a modpack that's publicly available on CurseForge.
Please be advised : this process deletes all files and data stored on your server, don't forget to create a Snapshot of your server beforehand from the Backups tab if necessary.
Go to the Versions tab then click Modpack. A few common modpacks are displayed but you can use the search bar to browse available modpacks.
Once you've found the modpack you'd like to play with, click the Install button.

A pop-up window will invite you to choose a version for the modpack. Finally, click the Reinstall the version button.

You'll be redirected to the Consele tab from where you can monitor the installation process. Once it's done, you can start the server !
