+## Blocking Issues
+
+Collaborators have the ability to block issues from getting implemented and landed into
+the project by commenting and explicitly including "-1" in the comment.
+When doing so, explain why you believe the pull request should not land along with
+an explanation of what may be an acceptable alternative course, if any.
