+/// Polymer.dart, the next evolution of Web UI,
+/// is an in-progress Dart port of the
+/// [Polymer project](http://www.polymer-project.org/).
+/// Polymer.dart compiles to JavaScript and runs across the modern web.
+///
+/// To use polymer.dart in your application,
+/// first add a
+/// [dependency](http://pub.dartlang.org/doc/dependencies.html)
+/// to the app's pubspec.yaml file.
+/// Instead of using the open-ended `any` version specifier,
+/// we recommend using a range of version numbers, as in this example:
+///
+///     dependencies:
+///       polymer: '>=0.7.1 <0.8'
+///
+/// Then import the library into your application:
+///
+///     import 'package:polymer/polymer.dart';
+///
+/// ## Other resources

+/// Example code, project status, and
+/// information about how to get started using Polymer.dart in your apps.

+// *** Important Note ***
+// This import is automatically replaced when calling pub build by the
+// mirrors_remover transformer. The transformer will remove any dependencies on
+// dart:mirrors in deployed polymer apps. This and the import to
+// mirror_loader.dart below should be updated in sync with changed in
+// lib/src/build/mirrors_remover.dart.
+//
+// Technically this annotation is not needed now that we have codegen for
+// expressions, but our test bots don't run pub-build yet. Until then, tests
+// might (transitively) have an import to smoke.mirrors, even though the code is
+// completely dead. This @MirrorsUsed annotation helps reduce the load on our
+// bots.
