-# This workflow is intended to keep scheduled GH Action workflows enabled
-# as a work-around for scheduled workflows being automatically disabled when
-# no repository activity has occurred in 60 days.
+# This workflow regularly disables and re-enables scheduled GH Action workflows.
+# Reasons:
+# 1. Ensures that email notifications for scheduled runs are configurable by the
+#    team under nextstrain-bot's account settings.
+# 2. Prevents workflows from being automatically disabled when no repository
+#    activity has occurred in 60 days.
