Most F/OSS projects probably don't want users who will ignore all but highly productized presentations of their work. That's almost certainly a counter-signal of a user's likelihood to file useful bug reports, let alone contribute.
But regarding this project in particular, you have lots of clues. There's a screenshot right there on the page. 'WM', short for 'window manager' is right there in the GitHub organization name. 'Compositor' is a standard term in this domain. It links to the most famous ever compositing window manager on its platform as a source of inspiration.
There are basically two groups of people that actively choose a specific window management stack instead of just choosing a whole operating system: advanced or growing Linux hobbyists, and the makers of Linux distros. Both of those groups will absolutely know what Wayland is, and will be able to tell what Wayfire is. And being a member of either requires more than the scant patience you've indicated you have for projects like this.
If you don't know what Wayland is and you're committed to not learning it instead of taking '2 minutes' to look it up, you're not the type to choose a window manager or configure a bespoke desktop environment.
