mkbook is my simpler alternative to mdbook which is a great tool, but for which I really dislike some of the decisions they took, such as relying on javascript for highlighting and navigation, and including a lot of bells and whistles such as javascript-based search.
This tool aims to work somewhat similarly to mdbook, but is generally intended to be a more minimal alternative that is customized more towards my needs and desires than anything else.
Still very WIP, but it can convert .md files into fancy-looking .html files, demo it by building the mkbook book by running: cargo run -- build -i docs-src -o docs and then serving the docs directory. Alternatively, view these generated docs here.
