1. Open a command prompt (open Start, search for "command prompt", then click it)
2. Run the appropriate command, depending on if you want audio or not
* No audio: :code:`python -m pip install Red-DiscordBot`
* Audio: :code:`python -m pip install Red-DiscordBot[voice]`
3. Once that has completed, run :code:`redbot-setup` to set up your instance
* This will set the location where data will be stored, as well as your
storage backend and the name of the instance (which will be used for
running the bot)
4. Once done setting up the instance, run :code:`redbot <your instance name>` to run Red.
It will walk through the initial setup, asking for your token and a prefix
