Raspberry Pi gets an open source educational manual
Been staring at that Raspberry Pi trying to figure out where to start? You're hardly alone. We've spent some time with the diminutive Linux machine and even tried to point you in the right direction when booting up your Pi for the first time. If you're looking for something a little more in depth than our own tutorial however, its worth checking out the just releasedRaspberry Pi Education Manual. The book, drafted by a team of teachers from Computing at School (CAS) and released under the Creative Commons licence, is available for free either through the Pi Store or at the source link in PDF form. It's a little more education-focused than say a tome like Getting Started with Raspberry Pi, but it's certainly an excellent introduction to the platform.
