What MkDocs is

MkDocs is a free static site generator for project documentation written in Markdown and configured with a YAML file. It builds documentation into static HTML that can be hosted on GitHub Pages, Amazon S3, or another static-file host. A local development server previews the site and reloads it after changes, while generated pages include search that can link to matching sections. The built-in mkdocs and readthedocs themes are available, alongside third-party and custom themes. Themes, plugins, Markdown extensions, and configuration options can shape the output. MkDocs uses Python-Markdown and requires a recent Python version and pip. Its command-line tools include commands to create, serve, and build projects, get dependencies, and deploy to GitHub Pages. The built-in mkdocs theme supports multiple locales, including English, German, Spanish, French, Japanese, and Chinese. Third-party themes and plugins execute code supplied by their authors, and MkDocs does not sandbox it. The software is available for Linux, macOS, Windows, and self-hosted use, and is distributed under the BSD license.

Who it suits

MkDocs suits people building project documentation sites from Markdown files who want static HTML output. It can work for teams publishing documentation to GitHub Pages, Read the Docs, or another static-file host.

What it does well

  • Free and distributed under the BSD license
  • Local preview reloads when documentation changes
  • Generated site includes search with section links
  • Static HTML can use multiple hosting providers

What to know first

  • Requires a recent Python version and pip
  • Third-party themes execute unsandboxed author code
  • Plugins execute unsandboxed author code

Limits

MkDocs is free, with a free plan. It requires a recent Python version and pip. Third-party themes and plugins execute code supplied by their authors, and MkDocs does not sandbox that code.

Getting started

  1. Install a recent version of Python and pip.
  2. Install MkDocs with pip install mkdocs.
  3. Create a documentation project with the command-line interface.
  4. Write documentation in Markdown and configure the project with a YAML file.
  5. Preview changes with the built-in development server.
  6. Build the static HTML site and deploy it to GitHub Pages or host it on a static-file service.

Verdict

MkDocs provides a command-line workflow for turning Markdown project documentation into static sites with search and theme options. Users should account for its Python requirements and the code-execution risks of third-party themes and plugins.
