+Updating releng/builder repo or global-jjb
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Follow these steps to update the releng/builder repo. The repo uses a submodule from
+a global-jjb repo so that common source can be shared across different projects. This
+requires updating the releng/builder repo periodically to pick up the changes. New
+versions of jjb could also require updating the releng/builder repo. Follow the
+previous steps earlier for updating jenkins-jobs using the
+`builder/jjb/requirements.txt <odl-jjb-requirements.txt_>`_ file. Ensure that the
+version listed in the file is the currently supported version, otherwise install a
+different version or simply upgrade using `pip install --upgrade jenkins-job-builder`.
+
+The example below assumes the user has cloned releng/builder to `~/git/releng/builder`.
+Update the repo, update the submodules and then submit a test to verify it works.
+
+.. code-block:: bash
+
+ cd ~/git/releng/builder
+ git checkout master
+ git pull
+ git submodule update --init --recursive
+ jenkins-jobs --conf jenkins.ini test jjb/ netvirt-csit-1node-openstack-queens-upstream-stateful-fluorine
