+## Dependencies
+
+Themes are written using Sass to keep things modular and reduce the need for repeated selectors across files. Make sure that you have the reveal.js development environment installed before proceeding: https://revealjs.com/installation/#full-setup
+
+## Creating a Theme
+
+To create your own theme, start by duplicating a ```.scss``` file in [/css/theme/source](https://github.com/hakimel/reveal.js/blob/master/css/theme/source). It will be automatically compiled from Sass to CSS (see the [gulpfile](https://github.com/hakimel/reveal.js/blob/master/gulpfile.js)) when you run `npm run build -- css-themes`.
+
+Each theme file does four things in the following order:
+
+1. **Include [/css/theme/template/mixins.scss](https://github.com/hakimel/reveal.js/blob/master/css/theme/template/mixins.scss)**
+Shared utility functions.
+
+2. **Include [/css/theme/template/settings.scss](https://github.com/hakimel/reveal.js/blob/master/css/theme/template/settings.scss)**
+Declares a set of custom variables that the template file (step 4) expects. Can be overridden in step 3.
+
+3. **Override**
+This is where you override the default theme. Either by specifying variables (see [settings.scss](https://github.com/hakimel/reveal.js/blob/master/css/theme/template/settings.scss) for reference) or by adding any selectors and styles you please.
+
+4. **Include [/css/theme/template/theme.scss](https://github.com/hakimel/reveal.js/blob/master/css/theme/template/theme.scss)**
+The template theme file which will generate final CSS output based on the currently defined variables.

+					<h2>Intergalactic Interconnections</h2>
+					<p>
+						You can link between slides internally,
+						<a href="#/2/3">like this</a>.
+					</p>
+				</section>
+
+				<section>
+					<h2>Speaker View</h2>
+					<p>There's a <a href="https://revealjs.com/speaker-view/">speaker view</a>. It includes a timer, preview of the upcoming slide as well as your speaker notes.</p>
+					<p>Press the <em>S</em> key to try it out.</p>
+
+					<aside class="notes">
+						Oh hey, these are some notes. They'll be hidden in your presentation, but you can see them if you open the speaker notes window (hit 's' on your keyboard).

+				</section>
+
+				<section>
+					<h2>Global State</h2>
+					<p>
+						Set <code>data-state="something"</code> on a slide and <code>"something"</code>
+						will be added as a class to the document element when the slide is open. This lets you
+						apply broader style changes, like switching the page background.
+					</p>
+				</section>
+
+				<section data-state="customevent">
+					<h2>State Events</h2>
+					<p>
+						Additionally custom events can be triggered on a per slide basis by binding to the <code>data-state</code> name.
+					</p>
+					<pre><code class="javascript" data-trim contenteditable style="font-size: 18px;">
+Reveal.on( 'customevent', function() {
+	console.log( '"customevent" has fired' );
+} );
+					</code></pre>
+				</section>
+
+				<section>
+					<h2>Take a Moment</h2>
+					<p>
+						Press B or . on your keyboard to pause the presentation. This is helpful when you're on stage and want to take distracting slides off the screen.
+					</p>
