+# Getting Started
+
+This guide explains how to create a bot for Discord using the `async-discord` gem.
+
+## Installation
+
+First, create a project with a gemfile, and add the `async-discord` gem to it:
+
+```bash
+$ bundle add async-discord
+```
+
+## Creating a Bot
+
+You will need to follow the [developer documentation](https://discord.com/developers/docs/intro) to create a bot and obtain a token. Once you have a token, you can create a bot like this:
+
+```ruby
+require 'async/discord'
+
+TOKEN = 'your-bot-token'
+
+Async::Discord::Client.open do |client|
+	client = client.authenticated(bot: TOKEN)
+	
+	client.gateway.connect do |connection|
+		identity = connection.identify(token: TOKEN)
+		
+		connection.listen do |payload|
+			case payload[:t]
+			when "MESSAGE_CREATE"
+				Console.info(self, "Received message!", payload: payload)
+			end
+		end
+	end
+end
+```
+
+This code will connect to the Discord gateway and listen for messages. When a message is received, it will log the payload to the console. You must make sure your bot is set up with the correct permissions to receive messages.
