There is a few wiki pages on github you can check out. If you want more tutorials or API just ask in the discussion section.
Version: 1.9.1
The titles make me crash. I am giving you a 1 star rating because of it. JK, its spigots fault for 1.11. I will give the 5 for this plugin actually working :D
Fantastic plugin!!! New update hype
These are great plugins that will allow you to give voters anything!
Most plugins are out-dated. This is a good plugin for anyone who needs a listener/give player item when voting plugin!
Author is awesome. Fixed a bug for me super quick and somehow puts up with my issues without getting irritated. Definitely one of the better plugin devs I've seen, and one of the best with free plugins.
Nice, anvil API! I hope, it will be implement in your other plugins like AdvancedMobControl and VotingPlugin. And I hope, you add also Chat API or book API.
