 Service Tagging
 ---------------
 Service tagging is used to specify which services are exercised by a particular
-test method. You specify the services with the ``tempest.test.services``
+test method. You specify the services with the ``tempest.common.utils.services``
 decorator. For example:
 
-@services('compute', 'image')
+@utils.services('compute', 'image')
 
 Valid service tag names are the same as the list of directories in tempest.api
 that have tests.

 Test class level resources should be defined in the `resource_setup` method of

+Cleanup is best scheduled using `addClassResourceCleanup` which ensures that

+            It can be used only once. Multiple entries will be ignored.

+
+        `setup_clients` is invoked after the credential provisioning step.
+        Client manager objects are available to tests already. The purpose
+        of this helper is to setup shortcuts to specific clients that are
+        useful for the tests implemented in the test class.
+
+        Its purpose is mostly for code readability, however it should be used
+        carefully to avoid doing exactly the opposite, i.e. making the code
+        unreadable and hard to debug. If aliases are defined in a super class
+        it won't be obvious what they refer to, so it's good practice to define
+        all aliases used in the class. Aliases are meant to be shortcuts to
+        be used in tests, not shortcuts to avoid helper method attributes.
+        If an helper method starts relying on a client alias and a subclass
+        overrides that alias, it will become rather difficult to understand
+        what the helper method actually does.

+
+        The use case for `resource_setup` is test optimization: provisioning

+
+        Some test resources have an asynchronous delete process. It's best
