Beginners should start with NOOBS. You can purchase a pre-installed NOOBS SD card from the PiFactory, or download NOOBS below and follow the NOOBS setup guide.
NOOBS is an easy operating system installer which contains Raspbian. It also provides a selection of alternative operating systems which are then downloaded from the internet and installed.
NOOBS Lite contains the same operating system installer without Raspbian pre-loaded. It provides the same operating system selection menu allowing Raspbian and other images to be downloaded and installed.
