mdBook — Create Books from Markdown Like Gitbook in Rust

What it is

mdBook is a Rust-based tool that generates online books from Markdown files. It is similar to Gitbook but faster, simpler, and requires no JavaScript runtime. The Rust project itself uses mdBook for its official documentation including the Rust Book, Cargo Book, and Tokio Tutorial.

This tool is ideal for open-source maintainers writing documentation, educators creating course material, and teams building internal knowledge bases. It produces clean, searchable HTML with a table of contents, chapter navigation, and theme support.

How it saves time or tokens

mdBook removes the complexity of documentation site generators. You write Markdown, define chapter order in a SUMMARY.md file, and run mdbook build. No npm install, no config files beyond the basics, no JavaScript bundler. The Rust binary compiles and serves instantly. For AI workflows, generating documentation content in Markdown that mdBook can render saves the overhead of learning framework-specific markup.

How to use

1. Install mdBook as a single binary.
2. Initialize a new book project.
3. Write chapters in Markdown.
4. Build or serve the book locally.

# Install mdBook
cargo install mdbook
# Or download pre-built binary from GitHub releases

# Create a new book
mdbook init my-book
cd my-book

# Edit src/SUMMARY.md to define chapters
# Write content in src/ directory

# Serve locally with hot reload
mdbook serve --open

# Build static HTML
mdbook build

Example

The SUMMARY.md file defines the book structure:

# Summary

[Introduction](README.md)

# Getting Started

- [Installation](getting-started/installation.md)
- [Quick Start](getting-started/quick-start.md)
- [Configuration](getting-started/configuration.md)

# Advanced Topics

- [Custom Themes](advanced/themes.md)
- [Preprocessors](advanced/preprocessors.md)
- [Backends](advanced/backends.md)

# Reference

- [CLI Commands](reference/cli.md)
- [Configuration Options](reference/config.md)

Each entry maps to a Markdown file that mdBook renders into a chapter.

Common pitfalls

• The SUMMARY.md file must list every chapter. Orphaned Markdown files not listed in SUMMARY.md will not appear in the built book.
• mdBook does not support advanced Markdown extensions like footnotes or definition lists out of the box. Use preprocessor plugins for extended syntax.
• Custom themes require understanding the Handlebars template format that mdBook uses.
• Search functionality requires JavaScript in the browser. If you disable JS, the search panel will not work.
• Deploying to GitHub Pages requires a CI step to build and push the book/ directory to the gh-pages branch.
