Make it clear that the plugin does not generate the world for you and you must generate your own prisons world and then assign the coordinates of all of the mines in the mines.yml. You also need to tell the plugin where the doors to each of your rooms are in the rooms.yml file, and this should also be specified in the documentation.
Also include in the releases, a world download of the sample world that is live on the Antares Server, so that people that download this plugin have a world to go along with it
