 should be submitted for review via the Gerrit tool, following
 the workflow documented at [http://wiki.openstack.org/GerritWorkflow](http://wiki.openstack.org/GerritWorkflow).
 
-Pull requests submitted through GitHub will be ignored.
+Gerrit is the review system used in the OpenStack projects.  We're sorry, but
+we won't be able to respond to pull requests submitted through GitHub.
 
 Bugs should be filed [on Launchpad](https://bugs.launchpad.net/swift),

+Recommended workflow
+====================
+
+ * Set up a [Swift All-In-One VM](http://docs.openstack.org/developer/swift/development_saio.html).
+
+ * Make your changes.
+
+ * Run unit tests, functional tests, probe tests
+   ``./.unittests``
+   ``./.functests``
+   ``./.probetests``
+
+ * Run ``tox`` (no command-line args needed)
