The actual guide is pretty sloppily written and doesn't outline all that much, along with not explicitly saying what you have to define at each step. It doesn't define what the different cases of the mal Lisp value type should be, for example, or when to implement pretty much all of the "optional" extensions it mentions in the first or second chapter.
