 /**
  * A library for writing dart unit tests.
  *
- * To import this library, specify the relative path to
- * pkg/unittest/unittest.dart.
+ * To import this library, use the pub package manager.
+ * Create a pubspec.yaml file in your project and add
+ * a dependency on unittest with the following lines:
+ *     dependencies:
+ *       unittest:
+ *         sdk: unittest
+ *         
+ * Then run 'pub install' from your project directory or using
+ * the DartEditor.
+ *         
+ * Please see [Pub Getting Started](http://pub.dartlang.org/doc)
+ * for more details about the pub package manager.
