First you need to create a user bot on Discord Developer Apps
Secondly, you must register your bot on your server. Use this link to register your bot by replacing CLIENT_ID with your bot client ID
https://discordapp.com/api/oauth2/authorize?client_id=CLIENT_ID&scope=bot
Finally download the bot and follow our Setup Guide!
