+Osha Specific Commandments
+------------------------------
+
+Logging
+-------
+
+Use the common logging module, and ensure you ``getLogger``::
+
+    from oslo_log import log
+
+    LOG = log.getLogger(__name__)
+
+    LOG.debug('Foobar')
+
+
+
+Properly Calling Callables
+--------------------------
+
+Methods, functions and classes can specify optional parameters (with default
+values) using Python's keyword arg syntax. When providing a value to such a
+callable we prefer that the call also uses keyword arg syntax. For example::
+
+    def f(required, optional=None):
+        pass
+
+    # GOOD
+    f(0, optional=True)
+
+    # BAD
+    f(0, True)
+
+This gives us the flexibility to re-order arguments and more importantly
+to add new required arguments. It's also more explicit and easier to read.

-After adding the notification driver, we can handle the failed nodes by triggering the driver to send notification directly to the admin ...
