Any guide on how to prepare for a recession?

I personally am worried about the AI bubble (my current job is very related to that), and whether that turns out to happen or not, I think it's important to be financially prepared for an eventual recession. I can think of some basics like having emergency funds, diversifying investments, etc, but beyond that, is there a guide that talks more about it? Either books, reddit posts, videos... just curious what people think about it
