What is Nova?
Nova is a server-side modding framework for Paper servers that aims to streamline adding custom content like items, blocks, guis, and more, without client-side modifications, using resource pack tricks.
As a server administrator, you can choose from a set of Nova addons, which will add content to the game.
Make sure to check out the Setup Guide!
You can find a list of frequently asked questions here.
