+ * HTML elements and other resources for web-based applications that need to
+ * interact with the browser and the DOM (Document Object Model).
+ *
+ * This library includes DOM element types, CSS styling, local storage,
+ * media, speech, events, and more.
+ * To get started,
+ * check out the [Element] class, the base class for many of the HTML
+ * DOM types.
+ *
+ * ## Other resources
+ *
+ * * If you've never written a web app before, try our
+ * tutorials—[A Game of Darts](http://dartlang.org/docs/tutorials).
+ * 
+ * * To see some web-based Dart apps in action and to play with the code,
+ * download
+ * [Dart Editor](http://www.dartlang.org/#get-started)
+ * and run its built-in examples.
+ *
+ * * For even more examples, see
+ * [Dart HTML5 Samples](https://github.com/dart-lang/dart-html5-samples)
+ * on Github.
