Installation and Setup of Operating System (Raspbian) - Raspberry Pi and Python tutorials p.2

description
In this Raspberry Pi tutorial, we're going to install and setup our operating system, Raspbian Assuming you've got your board, and an SD card, you're ready to carry on. Being a full computer, the Raspberry Pi uses an Operating System. While you can run headless (from a command line, no desktop), you can also have a GUI desktop if you like. There are quite a few choices for Raspberry Pi operating systems, but most people choose Raspbian, which is a Debian-based operating system that is optimized specifically for the Raspberry pi. This operating system is also most likely to support other packages that you may already be familiar with from other Linux distributions, so it makes for a good starting OS.
