+# 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.
+
+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.
+
+```
+Reveal.initialize({
+  // Display controls in the bottom right corner
+	controls: true,
+
+	// Display a presentation progress bar
+	progress: true,
+
+	// If true; each slide will be pushed to the browser history
+	history: true,
+
+	// Apply a 3D roll to links on hover
+	rollingLinks: true,
+
+	// UI style
+	theme: 'default', // default/neon
+
+	// Transition style
+	transition: 'default' // default/cube/page/concave/linear(2d)
+});
+```
