Is there any guide for ffi which is beginner friendly?

FFI seems to be a hard topic to grasp. So I would like to start with something that can help me internalize the basics and give me the necessary intuition for the topic. Thanks

Define "beginner friendly", that's what the answer depends on :smile:. Personally, I think the nomicon got a pretty decent intro

A while back I wrote up an FFI Guide, then was halfway through rewriting it before getting distracted by something shiny.
