Creating a Fretta Server

I cannot quite figure out how to set up a dedicated server for Fretta.

How do I go about setting up all the gamemodes and voting and such?

Just download the Fretta gamemodes and put them into your server’s gamemodes folder.
You don’t need to do anything about the gamemode voting, it’ll be there along with the map voting.

Also if you use a download server, you’ll need to load each gamemode to create the cache, and then upload it to the server.
