Licensing issue

[DarkSeraphim]

Give credit where credit is due. You pretty much copy pasted half the classes (if not more) from Bukkit.

Moreover, their license does not allow you to use it as it currently is used:

• There's no license and no copyright notice of their code
• You need to state what you've changed
• The project would have to be licensed as GPL v3

You're right, thank you. Firstly I've changed the LICENSE to match GPL v3.

Now what I need to do exactly? Documenting changes from the Bukkit configuration files?

[DarkSeraphim]

Documenting changes you made to the files you use from Bukkit I believe.

(Besides it'd probably be nice for the Bukkit team to note that you're using their YAML wrapper as well)

Ok, I've improved the README and added @author tag to each File.
