Setup

On Raspbian, setup is pretty simple with

   curl -sS get.pimoroni.com/displayotron | bash

You can then check out the examples and test out the scripts

   sudo ./joystick.py

While I haven't tried it yet, it does seem possible to use pip to install this on other OSes

   sudo pip install dot3k

On Non-Raspbian

Since using the above method doesn't seem to work on Arch Linux, we can do it simply with

   git clone https://github.com/pimoroni/displayotron.git
   cd displayotron/library/
   sudo make
