+# **what?**
+# When the core team triages, we sometimes need more information from the issue creator.  In
+# those cases we remove the `triage` label and add the `awaiting_response` label.  Once we
+# recieve a response in the form of a comment, we want the `awaiting_response` label removed
+# in favor of the `triage` label so we are aware that the issue needs action.
+
+# **why?**
+# To help with out team triage issue tracking
+
+# **when?**
+# This will run when a comment is added to an issue and that issue has to `awaiting_response` label.
