This book is for everyone who wants to get started with the Raspberry Pi。Even if you have some experience with other computers， you’ll quickly see that the Pi is different in many regards， and this book helps you avoid the most common pitfalls。You can choose from a variety of operating systems for the Pi， but this book’s focus is on Debian Linux (Raspbian)，because it is the most convenient choice for beginners。 If you’ve never worked with Linux before，you should start with Appendix 1， A Linux Primer，on page 101。 Even if you’ve worked with Linux before， you still might learn a few things， because running Linux on the Pi is different in some ways。Of course， you’ll get the most out of this book if you have a Raspberry Pi and follow all the book’s examples closely。
