Chromium OS ft. Docker
Chromium OS is cool. Chromium OS with crouton is cooler. Chromium OS with Docker is even cooler. This is specifically a guide for the HP Chromebook 13 G1 (aka HP Spyder Chromebook), but I can't think of any reason it wouldn't work with other devices. The Chromebook Pixel 2 (2015), for example...as you'll notice, the guide this was forked from assumed that machine.
