Installation is really straight forward, all you need to do is:
Download the plugin
Drop in your plugins folder
Reboot your server.
Vault Support
Vault support brings the ability to specify the [vault] action, thus providing the ability to take and add economy to your players based on the rewards.
WorldGuard support
Although it is a bit tricky to set it up this is what you need to do:
Create a region or use the one you already have
Allow the block-break flag
Allow the epicblocks-break flag
the block-break flag will allow all blocks to be broken inside a region, but EpicBlocks will only allow custom blocks, so you will not have to worry about players griefing your area!
