-* ``[skip ci]``: Within the HEAD commit will cause Cirrus CI to ***NOT*** execute
-  tests on the PR.  This is useful in basically two cases:  1) You're still working
-  and don't want to waste resources.  2) You haven't modified any code that would
-  be exercised by the tests.  For example, documentation updates (outside of code).
