 A CSS 3D slideshow tool for quickly creating good looking HTML presentations. Doesn't _rely_ on any external libraries but [highlight.js](http://softwaremaniacs.org/soft/highlight/en/description/) is included by default for code highlighting.
 
-Note that this requires a browser with support for CSS 3D transforms and ``classList``. If CSS 3D support is not detected, the presentation will degrade to less exciting 2D transitions. You could also use a polyfill for ``classList`` to make this work in < iOS 5 and < Safari 5.1, [here's one](https://github.com/remy/polyfills/blob/master/classList.js) from [@remy](https://github.com/remy).

+## Usage
 
-Markup heirarchy needs to be ``<div id="reveal"> <div class="slides"> <section>`` where the ``<section>`` represents one slide and can be repeated indefinitely. If you place multiple ``<section>``'s inside of another ``<section>`` they will be shown as vertical slides.
+### Markup
 
-At the end of your page, after ``<script src="js/reveal.js"></script>``, you need to initialize reveal. Note that all config values are optional.

-# History
+### API
+
+The Reveal class provides a minimal JavaScript API for controlling its navigation:
+
+- Reveal.navigateTo( indexh, indexv );
+- Reveal.navigateLeft();
+- Reveal.navigateRight();
+- Reveal.navigateUp();
+- Reveal.navigateDown();
+
+### States
+
+If you set ``data-state="someState"`` on a slide ``<section>``, "someState" will be applied as a class on the document element when that slide is opened. This allows you to apply broad style changes to the page based on the active slide.
+
+Furthermore you can also listen to these changes in state via JavaScript:
+
+```
+document.addEventListener( 'someState', function() {
+	// TODO: Sprinkle magic
+}, false );
+```
