+Recommonmark
+============
 
 A `docutils`-compatibility bridge to [CommonMark][cm].
 
 This allows you to write CommonMark inside of Docutils & Sphinx projects.
 
-## Why a bridge?
+Contents
+--------
+* [API Reference](api_ref.md)
+* [AutoStructify Component](auto_structify.md)
+
+Getting Started
+---------------
+This document is actually generated by recommonmark, and its source code can be used as a good reference.
+To see what you can get beyond the normal markdown syntax, checkout [AutoStructify Component](auto_structify.md).
+
+Why a bridge?
+-------------
 
 Many python tools (mostly for documentation creation) rely on `docutils`.
 But [docutils][dc] only supports a ReStructuredText syntax.
@@ -21,7 +33,8 @@ recommonmark uses the [python implementation][pcm] of [CommonMark][cm] while
 Both output a [`docutils` document tree][dc] and provide scripts
 that leverage `docutils` for generation of different types of documents.

+---------------
 
 recommonmark is mainly derived from [remarkdown][rmd] by Steve Genoud and
 leverages the python CommonMark implementation.
