Welcome!
Once you have installed this plugin, you will get two types of hacks: AntiKnockback and Fly. The only thing what you need to do is typing /hacks and then there will open a menu where you can choose what kind of hacks you want to turn on/off. A menu like this:
You can click on the items in the menu. If you click on an item, your hack will turn on and the item will start glowing. For turning your hack off, just do the same: clicking on the item.
For getting acces to /hacks, you need to be OP or have the permission "perm.hack".
That's all!
Enjoy!
