Bukkit

Download Apocalyptic.jar and SQLibrary and add to your /plugins/ folder. If you want world generation, add this snippet to the bottom of bukkit.yml.

worlds: 
  <world>: 
    generator: Apocalyptic

Where <world> is the name of the world you want to generate.

If you use Muiltiverse, run this command to make a new Apocalyptic world.

/mv create <world> normal -g Apocalyptic

Again, where <world> is the name of the world you want to generate.

Run the server. This will generate some of the world and create config files. Set up the configuration files to your liking. I am currently working on a configuration guide.

Done! Have fun!
