mdBook
What it is
mdBook is a free command-line tool for turning Markdown into books, including product or API documentation, tutorials, and course materials. It builds static output files in a book directory that can be transferred to a web service. Integrated search and syntax highlighting for code blocks help readers navigate and read technical material, while theme files let authors change output formatting. Preprocessors can add custom syntax or alter content, and backends can render to multiple formats. The mdbook test command checks Rust code samples in a book. The documentation describes using GitHub Actions or GitLab CI/CD to test and deploy books automatically. Developers can also import mdBook libraries or use its plugin mechanism to build custom tools and output backends. Linux, macOS, and Windows are listed platforms. Building from source requires Rust and Cargo, with Rust 1.88 as the stated minimum. The project directs issue reports and feature requests to its GitHub issue tracker and relies on community contributions for fixes and additions.
