Hello HN, I'd really like to learn the way AOSP forks are built for different hardware. The sites of these forks seem quite hostile towards anyone who's going to ask them about it. I understand that they don't want their mailbox flooded with questions about it, but I would like to know:

What are the right questions to ask/google.

And I know that this quest is probably too complicated for normal human beings (unlike the wizards that do it over there) but I want to try it out.
