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. There's a single configuration file named mkdocs.yml and a folder named docs that will contain your documentation source files. (mkdocs.org).

MkDocs comes with a built-in dev-server that lets you preview your documentation as you work on it. Make sure you're in the same directory as the mkdocs.yml configuration file, and then start the server by running the mkdocs serve command. Open up http://127.0.0.1:8000/ in your browser, and you'll see the default home. The dev-server also supports auto-reloading, and will rebuild your documentation whenever anything in the configuration file, documentation directory, or theme directory changes.

mkdocs build

This will create a new directory, named site with the Documentation.
