-If you are a Patreon: You automatically join the server! Yaaay, easy peezy!
-If you are a Twitch Sub: You need to go to Settings > Connections > Connect your twitch account and you'll already have full access to the server! Yaaaay, not so easy peezy but still doable!
-If you are neither of those 2: You can still check the 📢-announcements and 🔴-stream-alerts channels! When you get gifted a sub on stream you will be able to participate, or if you become a Patreon!
