+<h1 id="get_ready_to_build_chrome_apps_">About this Codelab</h1>
 
-<p>Chrome apps are written in HTML5, JavaScript, and CSS, just like web apps.
-But they look and behave more like native apps, and they have super-powerful capabilities,
-like the ability to interact with network and hardware devices, media tools, and much more.</p>
+<p>The goal of this codelab is to
+get you building Chrome packaged apps fast.
+We&#39;ve done our best to capture some of the trickier parts
+to the development process
+keeping the samples simple and straightforward.
+Once you&#39;ve completed this codelab,
+you will have a simple Todo app.

+All sample code can be downloaded from the
+<a href="https://github.com/GoogleChrome/chrome-app-codelab">chrome-app-codelab repository</a>. 
+Each lab builds upon the previous lab's sample code.
+To see how the Todo app changes as you work through the lab,
+upload the code from the extensions management page
+and launch the app
+(see <a href="first_app.html#five">Create Your First App tutorial</a>).
+</p>
 
-<p>Chrome apps are still in developer preview-- we know they aren&#39;t perfect. But we&#39;re trying to do something new here, bridging together the native and web experience, giving developers choice and users the best experience possible.</p>
+<p class="note">
+<strong>Note: </strong>
+After the first launch,
+ChromeOS and Windows users can see their apps in the
+<a href="http://blog.chromium.org/2013/02/chrome-app-launcher-developer-preview.html">Chrome app launcher</a>.
+Other platforms can see installed apps on a new Chrome tab
+or by navigating to <code>chrome://extensions</code>.
+</p>
 
-<p>For Chrome apps to succeed, we need and want your feedback and we don&#39;t want you to have to go in circles to provide it.
-We appreciate your feedback either at the <a href="http://groups.google.com/a/chromium.org/group/chromium-apps">chromium-apps group</a> or, if appropriate, as a bug filled at the <a href="http://crbug.com/new">official issue tracker</a></a>.</p>

+You can choose to write your sample Todo app
+using a preferred
+<a href="app_frameworks.html">MVC framework</a>.
+Starting in
+<a href="app_codelab3_mvc.html">3 - Create MVC</a>,
+we've provided sample code in pure JavaScript
+and using
+<a href="http://angularjs.org">AngularJS</a>.
+We've also included code snippets for both versions
+throughout the codelab docs.
+As you continue through the codelab,
+make sure your sample code builds from the same version.
+</p>
+
+<p class="note">
+<strong>Want to add a framework?</strong><br>
+You can always create your own Todo app
+in a different preferred framework.
+And we would be very happy to include it
+in the sample code repository.
