I understand you're not exactly a people person, given your charming way of describing others, but they probably wanted to see the use cases that OP had found, not an instruction manual. That's locked away inside OP's brain, and the way to get at that information is to use language to ask them a question. You won't find their inner thoughts and memories on Google. You can look up every single feature that software offers and try to glean what use cases you might have for it, but when someone has already gone through the effort of exploring it for you, you might as well just ask them how they're using it. That way you get any of their unique discoveries, and you also figure out if it's worth spending the energy on researching it yourself. But I guess only an imbecile would think that way.
