Thank you for this project, @kip-hart. I was about to open an issue about the documentation formatting, but I thought I'd check the open PRs first. Glad I did! You're a step ahead of me. I'm not entirely sure this patch fixes all of the issues I see in the documentation, but I'll be glad to see it improved.
