How to Install Chromium OS on RockPro64

While single-board computers (SBCs) such as the Raspberry Pi run Linux desktops extremely well, many non-Linux distributions (distros) provide greater choice for desktop use. For instance, you can make an Android desktop or run the likes of FreeBSD, OpenBSD, and RISC OS on many maker boards. Chromebooks have become increasingly popular because of their lightweight desktop environment as well as ease of use. Although tons of Chrome OS laptops are available off-the-shelf, you can instead make your own DIY (do-it-yourself) Chrome OS desktop by installing Chromium OS on the RockPro64!
