While you are waiting for Raspberry Pi User Guide book to be released, you might want to order the Meet the Raspberry Pi eBook.
This is the shorter, cut-down version of the book, which is to be followed shortly by a much longer book with more tutorials, more programming, and more physical computing (and longer versions of the existing chapters). This shorter version is ideal for beginners, and will talk you through setting up your Raspberry Pi from scratch, and get you to a position where you can start using your Raspberry Pi like a pro. If you are a more advanced user, you may prefer to wait for the full version of the book to come out.
It’s currently available on Amazon for £3.29, a bargain if ever there was one. Click below to order your copy and get it in seconds!Check out what happened at the Q&A session with the Raspberry Pi Foundation
