>This web page does a terrible job representing the necessary install steps. It looks super combined but can be combined into three or maybe four commands.

  git clone <git-repository>; make; make update-assets

It's literally three commands, assuming you have all the dependencies like I did, all of which is written clearly on the project page. Even if you don't have the dependencies, it's trivial to install them. I don't understand what's so terrible about it.
