I started with Markdown and gitbook initially (the old version of gitbook), and then switched to Pandoc & XeLaTex engine with the mixture of Markdown and LaTex. I only did the "cat" and "ref" boxes in LaTex, everything else is Markdown. I also use some Ruby for preprocessing (when building other formats), previews, etc. Someone submitted my post on that to HN a while ago so there is some discussion here: https://news.ycombinator.com/item?id=28594863 https://news.ycombinator.com/item?id=28594863
