+
+------------------------
+Setting up your instance
+------------------------
+
+Run :code:`redbot-setup` and follow the prompts. It will ask first for where you want to
+store the data (the default is :code:`~/.local/share/Red-DiscordBot`) and will then ask
+for confirmation of that selection. Next, it will ask you to choose your storage backend
+(the default here is JSON). It will then ask for a name for your instance. This can be
+anything as long as it does not contain spaces; however, keep in mind that this is the
+name you will use to run your bot, and so it should be something you can remember.
+
+-----------
+Running Red
+-----------
+
+Run :code:`redbot <your instance name>` and run through the initial setup. This will ask for
+your token and a prefix.
