Angstrom is the default Linux distribution that is pre-installed on the eMMC on the BeagleBone Black. It's a stripped down version of Linux specifically designed for embedded devices.

To start with, download the latest version of Angstrom for the BeagleBone Black. You can find the latest version at the BeagleBoard Latest Images page. Once you've downloaded the file, you'll want to jump to the section for your specific OS (Mac OS X, Linux, Windows).
