The only time I really read some docs is if I've been stuck on one particular problem for a while.
I suspect that 90% of the time, if it isn't in a codeblock I don't read it.
However often that happens amid the many misadventures of using the assortment of things that we apply for our daily grind.
I skim, particularly those parts related to configuration or access control. Taking some small pleasure reading well written or genuinely informative parts.
Most of the time, I skim them to familiarize myself with what they're covering and where they're covering it. Then when I need to clear something up or learn something, I have a clue about where in the docs to look (or to look elsewhere).
