MkDocs
Project documentation with Markdown.
MkDocs is a fast, simple and downright gorgeous static site generator that's geared towards building project documentation. Documentation source files are written in Markdown, and configured with a single YAML configuration file. Start by reading the introductory tutorial, then check the User Guide for more information.
Features
Great themes available
There's a stack of good looking themes available for MkDocs. Choose between the built in themes: mkdocs and readthedocs, select one of the third-party themes (on the MkDocs Themes wiki page as well as the MkDocs Catalog), or build your own.
Easy to customize
Get your project documentation looking just the way you want it by customizing your theme and/or installing some plugins. Modify Markdown's behavior with Markdown extensions. Many configuration options are available.
Preview your site as you work
The built-in dev-server allows you to preview your documentation as you're writing it. It will even auto-reload and refresh your browser whenever you save your changes.
Host anywhere
MkDocs builds completely static HTML sites that you can host on GitHub Pages, Amazon S3, or anywhere else you choose.
