+<div class="description"><p>The <code>ngController</code> directive assigns behavior to a scope. This is a key aspect of how angular
+supports the principles behind the Model-View-Controller design pattern.</p>
+
+<p>MVC components in angular:</p>
+
+<ul>
+<li>Model — The Model is data in scope properties; scopes are attached to the DOM.</li>
+<li>View — The template (HTML with data bindings) is rendered into the View.</li>
+<li>Controller — The <code>ngController</code> directive specifies a Controller class; the class has
+methods that typically express the business logic behind the application.</li>
+</ul>
+
+<p>Note that an alternative way to define controllers is via the <code>&lt;a href="api/ng.$route"&gt;&lt;code&gt;ng.$route&lt;/code&gt;&lt;/a&gt;</code>
+service.</p></div>

+<ul class="parameters"><li><code ng:non-bindable="">ngController – {expression} – </code>
+<p>Name of a globally accessible constructor function or an
+<a href="guide/expression">expression</a> that on the current scope evaluates to a
+constructor function.</p></li>
+</ul>
+</div>
+<h2 id="Example">Example</h2>
+<div class="example"><p>Here is a simple form for editing user contact information. Adding, removing, clearing, and
+greeting are methods declared on the controller (see source tab). These methods can
+easily be called from the angular markup. Notice that the scope becomes the <code>this</code> for the
+controller's instance. This allows for easy access to the view data from the controller. Also
+notice that any changes to the data are automatically reflected in the View without the need
+for a manual update.
