Very valid question. I have tested it a little! I wrote it because a less technical tech writer was asking me a ton of questions, and he found it helpful. I also got a non-technical marketing person to review it, and she said she was able to learn a lot from it (those are the two people I thank in the intro)

It's obviously not going to get someone up and running: it's not a hands-on practical guide. But there are already quite a lot of those out there (for instance, most static site generators have acceptable getting started docs) The aim is to provide the missing conceptual info that's usually assumed by the creators of tools, but that not all tech writers have. Ideally, it should make them feel more comfortable following, say, an intro to git tutorial, because they have a bit more context/explanation backing them up.

Great that you road-tested it! Real world data is always going to be higher quality than my drive-by opinion!
