Welcome to people who saw the Tasty Tech article in Make Magazine!
The article says to come to this site to get the latest disk image. Unfortunately the image I currently have is huge (due to my expanding it to fill the SD card), and I don’t know how to shrink it, and I should really create a stripped-down image.
My plan is to do that. But in the meantime, if you just install a normal Raspberry Pi image you will be on your way. I will update with a full set of instructions ASAP.
In the meantime, check out the GitHub repository for case designs, sample code, and more.
