Chapter 1. Getting Started with Raspberry Pi

While there are many operating systems (OS) available for the Raspberry Pi, the Raspberry Pi Foundation (http://www.raspberrypi.org) offers Raspbian as the primary OS. Raspbian (http://www.raspbian.org) is based on yet another operating system called Debian, which is built on a Linux kernel for the Raspberry Pi.
