 Tempest Specific Commandments
 ------------------------------
 
-[T101] If a test is broken because of a bug it is appropriate to skip the test until
-bug has been fixed. However, the skip message should be formatted so that
-Tempest's skip tracking tool can watch the bug status. The skip message should
-contain the string 'Bug' immediately followed by a space. Then the bug number
-should be included in the message '#' in front of the number.

-Example::
-
-  @testtools.skip("Skipped until the Bug #980688 is resolved")

+Test skips because of Known Bugs
+--------------------------------
+
+If a test is broken because of a bug it is appropriate to skip the test until
+bug has been fixed. You should use the skip_because decorator so that
+Tempest's skip tracking tool can watch the bug status.
+
+Example::
+
+  @skip_because(bug="980688")
+  def test_this_and_that(self):
+    ...
+
 Guidelines
 ----------
 - Do not submit changesets with only testcases which are skipped as
