@tomkennedy513 sorry about the red integration test, we have this check if all examples have a test. Mostly works the other way around and checks if we remembered to increase the number...

@edwardstudy Added doc.

@manno Is there something we should do to fix the test failures? Is there a number we should bump somewhere?
