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, and etc.
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
