+Keystone Style Commandments
+===========================
+
+- Step 1: Read the OpenStack Style Commandments
+  http://docs.openstack.org/developer/hacking/
+- Step 2: Read on
+
+Keystone Specific Commandments
+------------------------------
+
+- Avoid using "double quotes" where you can reasonably use 'single quotes'
+
+
+TODO vs FIXME
+-------------
+
+- TODO(name): implies that something should be done (cleanup, refactoring,
+  etc), but is expected to be functional.
+- FIXME(name): implies that the method/function/etc shouldn't be used until
+  that code is resolved and bug fixed.
+
+
+Logging
+-------
+
+Use the common logging module, and ensure you ``getLogger``::
+
+    from oslo_log import log
+
+    LOG = log.getLogger(__name__)
+
+    LOG.debug('Foobar')
+
+
+AssertEqual argument order
+--------------------------
+
+assertEqual method's arguments should be in ('expected', 'actual') order.
+
+
+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.
