Set up your Discord application and bot

1. Go to the Discord Developer Portal and login as necessary.
2. Create an app. Enter a name for your app and press Create. Take note of the application ID (also known as the client ID) of your bot on this initial screen.
3. On the left hand sidebar click Bot. There's a Token section on the Bot page, which allows you to copy and reset your bot's token. Reset the token and then then take note of that token (but keep it safe - it is dangerous).
4. Customize the name and profile picture of the bot as desired.
5. Turn on the "SERVER MEMBERS INTENT" switch on the Bot page.
6. Replace your client ID into this URL, then add the bot to your server: https://discord.com/oauth2/authorize?client_id=INSERT_CLIENT_ID_HERE&scope=bot&permissions=2164345872
7. Save the client ID and bot token to your .env as necessary.
