"Raspberry Pi New Out Of Box Software (NOOBS) microSD Card and SD Card Adapter — Debian Jessie
The latest version of NOOBS has been upgraded to enhance performance and user experience, using the Debian Jessie version of the Raspbian operating system.
As the Raspberry Pi was created to educate children about computing and programming, it was important to make it easy to set up. New Out Of Box Software (NOOBS) helps you set up your Pi and is available pre-installed on a microSD flash memory card, which also doubles up as an SD card adaptor. To get started, connect your Pi to a keyboard, mouse, power supply and screen and place the NOOBS card into the microSD card slot. Your next step is to install the operating system that you would like to use on your Pi.
