Read the readme, consider myself a mostly-not-total-idiot. Would buy author a beer to add a whole two sentences to illuminate what wozman is. If it's just that niche and I'm ignorant feel free to ignore me.
Ben Eater has a number of very informative videos on Wozmon on YouTube - what it is, how it works and and getting it to work on a home built 6502 machine, literally stepping through the assembly:
I find it a little weird that these comments always come up on hackernews… if you type "wozmon" in your URL bar and hit enter to search, pretty much _all_ the results are pertinent and helpful.
To add to your suggestion for the README: if this is indeed an "instruction by instruction rewrite" then it would also be helpful to include a canonical link to the original 6502 source. (Found a version here: https://gist.github.com/nobuh/1161983)
It's the boot ROM that came with the Apple I. It was pretty big for the time given that in those days, computers didn't come with flash, so you had to bootstrap programs with dip switches and the like. The Apple I came with wozmon on ROM, which provided a (VERY) minimal prompt to edit/view memory and run programs from it.
