So, what's this book actually gonna teach you?

My goal is certainly not just showing off the crate. Programming for the GBA is weird enough that I'm trying to teach you all the rest of the stuff you need to know along the way. If I do my job right then you'd be able to write your own crate for GBA stuff just how you think it should all go by the end.

Overall the book is sorted more for easy review once you're trying to program something. The GBA has a few things that can stand on their own and many other things are a mass of interconnected concepts, so some parts of the book end up having to refer you to portions that you haven't read yet. The chapters and sections are sorted so that minimal future references are required, but it's unavoidable that it'll happen sometimes.

The actual "tutorial order" of the book is the Examples chapter. Each section of that chapter breaks down one of the provided examples in the examples directory of the repository. We go over what sections of the book you'll need to have read for the example code to make sense, and also how we apply the general concepts described in the book to the specific example cases.
