Your Raspberry Pi needs an operating system to work. This is it. Raspberry Pi OS (previously called Raspbian) is our official supported operating system.
Raspberry Pi OS is a free operating system based on Debian, optimized for the Raspberry Pi hardware, and is the recommended operating system for normal use on a Raspberry Pi. The OS comes with over 35,000 packages: pre-compiled software bundled in a nice format for easy installation on your Raspberry Pi.
