+# Inviting the Bot
+
+It's quite simple really. Just follow the steps below:
+
+1. Join a Discord server that already has Blitzkrieg installed or [the official Discord Server](https://discord.gg/nDt7AjGJQH).
+2. Click on the bot's profile.
+3. Click the "Add to Server" button under the bot's name and ID.
+4. Select what server you want it in and see what permissions you seem fit for the bot.
+
+Voila! You're ready to go.
