What it is

mdBook is a free command-line tool for creating books from Markdown, including product and 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 examples, while theme files allow formatting changes. Preprocessors can add custom syntax or modify content; backends can render output to multiple formats. The `mdbook test` command tests Rust code samples in a book. Project 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 tooling and output backends. It runs on Linux, macOS, and Windows, and Markdown is its source input. Building from source requires Rust and Cargo, with Rust 1.88 as the stated minimum. The project directs issues and feature requests to its GitHub issue tracker and relies on community contributions for bug fixes and added features. The free, open-source plan is licensed under MPL-2.0.
