Yes the config files are described in manual pages though, remember that most of the users that worked on this were working on green-screened text terminals only a few years earlier. So this wasn't a big leap for them and more of a natural transition. But I also remember it took me some time to figure it out. Especially because it required logging in and out to test it, and if there was a big mistake the login would fail and I'd have to jump into a text shell to fix it :P
