Documentation is super important for complex things. I feel like it’s highly underrated by many otherwise great open source projects, to the severe detriment of the project. Nice to see an explicit focus on it.
Underrated in proprietary and non-software tech, too. It's horrible when infrequent tasks turn into bespoke shitshows every time they crop up because nobody wrote down how to solve the problem. Having to figure things out from scratch every time is ridiculously inefficient. Even worse if it leads to customers having slightly different copies of the same kind of software or device configuration because there's no documented process to follow. I know from experience.
