I'm reading through now, and would love to contribute. I've been trying to break into this space (systems programming, especially OS and compilers) for a long time and the biggest hurdle for me has been to actually do it. I really appreciate that this project is focused on explaining just enough to jump in, complemented with nods to further resources that can add on to whatever knowledge the reader brings. Steve, thanks for all your work on this and with Rust. Your attitude toward teaching and your writing ability go a long way in encouraging people to learn and in having the lesson be worthwhile.
