I no longer use a tiling window manager, used to use AwesomeWM for a decade or something before though, tiny disclaimer.

What exactly is the "hellish" parts of that documentation page? It seems to be explaining the main concepts you need to understand, how to access them, doesn't have any fluff, and doesn't have anything out of the ordinary really, but again, I might be reading it with very rose-colored glasses, so curious to hear what sticks out as "hellish" from that page.
