+<p>Implementing a cool idea is a great start toward an app that delights users,
+but it's just the beginning. The next step is maximizing your app's performance.
+For example, users want apps that:</p>
+
+<ul>
+   <li>Use power sparingly.</li>
+   <li>Start up quickly.</li>
+   <li>Respond quickly to user interaction.</li>
+</ul>
+
+<p>This section provides you with the know-how you need in order to make
+your apps not only cool, but also performant. Read on to discover how to
+develop apps that are power-thrifty, responsive, efficient, and well-behaved.</p>
