Once you have found the modpack you want to install, press the install button.
Select your version, and whether you want to Delete files or not. Keep in mind, this is irreversible. So make backups if you have not already.

Press Install modpack, it may take a few moments to install.
Enjoy the new modpack.
Uploading a Modpack
If you have a modpack that isn't available on any of our providers or are using a custom modpack to play with friends, you'll need to upload it via SFTP.
SFTP Clients
Read our existing guide on how to connect and upload your server with SFTP.
After uploading your zipped modpack, navigate to the File Manager, click on the uploaded file, and select Unarchive.

Custom Modpacks
Use custom modpacks at your own risk. Ensure you've done proper research and are using compatible mods—otherwise, you may encounter server issues, client-side problems, or crashes.
