> But when writing a book, pretty soon you run into things that Markdown doesn’t natively know how to do, and so you have to either look for extra tooling to fill in the gaps, or build support for those things yourself. There are open source projects that address some of this, but I didn’t see anything that would do everything I needed.

I'm surprised there's no mention of Pandoc, which does pretty much what the author wanted (at least at a high level) and works with markdown:
