mkbook is my simpler alternative to mdbook which is a great tool, however 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.
If you’re not familiar with mdbook, mkbook is a tool to convert a collection of Markdown files into a static website / book which can be published online. It was created to help me write documentation with minimum fuss while presenting it in an easy-to-consume manner.
