To setup the plugin you need to create a discordbot. To do that you need to visit this site:
https://discord.com/developers/applications Then you need to put the bots token into the config.yml. Afterwards you need to setup your groups. For this go into the discord.yml and register your groups. Now go ingame and type /setup if everything worked you are ready to go. Give the players the permission like showed in the discord.yml.
This is a extreme short description of the setup, please visit the Wiki or watch my video to use the full potential of the plugin.
