Can you explain what that (Solus) is? The website is rather light on details. Maybe a distribution. With three different DE editions, one being 'home-grown'.

I haven't found any information about the history of the project, if it's built from scratch or based on another distribution's work. Can't even figure that out by looking at the 'how to install software' documentation - it just gives a screenshot of a GUI package installer, no clue what the package manager is.

Searching Google for Solus (or Solus Project) comes up empty or with a survival game based on the Unreal 4 engine.

What is Solus?

Edit: While their website answered none of my questions, distrowatch and wikipedia did. Started as Debian based distribution, seems to be something completely new/different now.
