Pack Installation

When you download the code as a .zip file from GitHub, make sure to extract the file and install the folder inside it. GitHub tends to package an extra folder inside the .zip, so the pack will not load if that is the case. In addition, make sure to set generate-structures to false before you start/restart your server, as Terra will try to locate a suitable place for Strongholds to generate, which of course will not succeed and the server will crash, due to the generation being in the Nether. In a future version of Terra, custom structures will be supported and hopefully will fix this issue.

Other than that, simply install this pack like any other Terra generation pack. Add these lines to the end of Bukkit.yml. The ID of the pack is TARTARUS. However, rather than specifying the pack to generate in world, you would insert world_nether:

worlds:
  world_nether:
    generator: Terra:TARTARUS

Obviously, if your Nether world name is named something different, you would rename it to that instead.
