Regolith is available as a stand-alone ISO that can be installed as a complete Linux operating system, and as a "personal package archive" (PPA) that installs the Regolith desktop into an existing Ubuntu 18.04, 20.04, or 21.04 system. This page provides a quick start for installs and upgrades but more detailed documentation is available.
