+Testing notes
+=============
+
+
+build-integration-branch
+------------------------
+
+Setup
+^^^^^
+
+#. Create a github token at `<https://github.com/settings/tokens>`_
+   and put it in ``~/.github_token``.  Note that only the
+   ``public_repo`` under the ``repo`` section needs to be checked.
+
+#. Create a ceph repo label `wip-yourname-testing` if you don't
+   already have one at `<https://github.com/ceph/ceph/labels>`_.
+
+#. Create the ``ci`` remote::
+
+     git remote add ci git@github.com:ceph/ceph-ci
+
+Using
+^^^^^
+
+#. Tag some subset of `needs-qa` commits with your label (usually `wip-yourname-testing`).
+
+#. Create the integration branch::
+
+     git checkout master
+     git pull
+     ../src/script/build-integration-branch wip-yourname-testing
+
+#. Smoke test::
+
+     make && ctest -j12
+
+#. Push to ceph-ci::
+
+     git push ci $(git rev-parse --abbrev-ref HEAD)
+
