+Workflow Overview
+*****************

+.. image:: workflow.png
+
+
+To test a change in Ceph, start by pushing a branch with your changes to the
+`ceph-ci`_ repository. This will automatically trigger the Jenkins process 
+to build Ceph binaries - the status of the build can be observed on `Shaman`_. 
+These built packages will be uploaded on `Chacra`_. 
+
+To schedule a Teuthology integration test against this new build, you will 
+need access to the Sepia lab. Once you have access, log into the Teuthology 
+machine and complete the one-time initial Teuthology setup required to run 
+Teuthology commands. After the setup, use the ``teuthology-suite`` command to schedule 
+a Teuthology run. In this command, use the ``-c <ceph-ci branch name>`` option to 
+specify your build. The results of your test can be observed on `Pulpito`_. 
+Log into a `developer playground machine`_ to review the Teuthology run's archive logs.

+Pushing to the ceph-ci repository
+*********************************

+Follow these steps to push to the ceph-ci repository. After pushing, a new build will 
+automatically be scheduled.

+1. Add the ceph-ci repository as a remote to your local clone of the Ceph repository:

+
+2. Push your branch upstream by running a command of the following form:
+
+   .. prompt:: bash $
+
+       $ git push ceph-ci wip-yourname-feature-x
