+Serving the UI build from the distribution directory
+----------------------------------------------------
+* To serve the UI from the ``treeherder-ui/dist`` directory, from the ``treeherder-ui`` directory run:
+
+.. code-block:: bash
+    > grunt build
+
+
+ This will build the UI by concatenating and minifying the js and css and move all required assets to a directory called ``dist`` in the repository root of ``treeherder-ui``.
+
+* In ``treeherder-service/Vagrantfile`` uncomment this line:
+
+.. code-block:: ruby
+
+    puppet.manifest_file = "production.pp"
+
+ this puppet manifest sets the web application directory to the ``dist`` directory.
