+~~~~~~~~~~~~~~~~~~~
+
+Using the ``stopwatch`` helper, you are able to time parts of your template
+and display it on the timeline of the WebProfilerBundle::
+
+    <?php $view['stopwatch']->start('foo') ?>
+    ... things that gets timed
+    <?php $view['stopwatch']->stop('foo') ?>
+
+.. tip::
+
+    If you use the same name more than once in your template, the times are
+    grouped on the same line in the timeline.
