+      <p>The NgAnimate module is a port with modifications of the original
+        AngularJS animation module. The default implementation does nothing.
+        It simply provides hooks into the angular subsystem. Adding
+        <code>NgAnimateModule</code> however is a whole different story. Once
+        added it allows you define and run css animations on your elements with
+        pure CSS.</p>
