 credentials management, testresources and so on. These facilities, MUST be able
 to work even if just one ``test_method`` selected for execution.
 
+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 decorator.
+For example:
+
+@services('compute', 'image')
+
+Valid service tag names are the same as the list of directories in tempest.api
+that have tests.
+
+For scenario tests having a service tag is required. For the api tests service
+tags are only needed if the test method makes an api call (either directly or
+indirectly through another service) that differs from the parent directory
+name. For example, any test that make an api call to a service other than nova
+in tempest.api.compute would require a service tag for those services, however
+they do not need to be tagged as compute.
+
 Guidelines
 ----------
 - Do not submit changesets with only testcases which are skipped as
