Just Enough Finance for Developers?

i don't know if anyone has a book that they recommend where people were developers can get just enough finance. I think there's some on hackernes, some pepl on hapternews have asked this exact same question. Am, there's a lot of personal finance for people, which is like a setting up for ward case and stuff like that. That's not the focus of what we're doing here to day. We're doing business analysis andnd understanding financial matics.
