+
+<p>A <code>Dial</code> can be created easily and rendered into existing markup.</p>
+
+<h4 id="the-markup">The Markup</h4>
+<p>
+<strong>Note:</strong> be sure to add the <code>yui3-skin-sam</code> classname to the
+page's <code><body></code> element or to a parent element of the widget in order to apply
+the default CSS skin. See <a href="http://yuilibrary.com/yui/docs/tutorials/skins/">Understanding Skinning</a>.
+</p>
+<pre class="code prettyprint"><body class="yui3-skin-sam"> <!-- You need this skin class --></pre>
+
+<p>This example includes an element to contain the Dial and a text input field.</p>

+<input id="myTextInput" value=""/></pre>
+
+
+<h4 id="the-javascript">The JavaScript</h4>
+
+<p><code>Dial</code> extends the <code>Widget</code> class, following the same pattern
+as any widget constructor, accepting a configuration object to
+set the initial configuration for the widget.</p>
+
+<p>After creating and configuring the new <code>Dial</code>,
+call the <code>render</code> method on your <code>Dial</code> object passing it
+the selector of a container element.
+This renders it in the container and makes it usable.</p>
+
+<p>Some commonly used configuration attributes are shown below.
+</p>

+
+<p>To keep the Dial's value and a text input value in sync, we need to subscribe to events on both the text input and the Dial.</p>
