+**Notification Urgency Level**
+
+By default non zero exit codes lead to notifications marked as critical.
+On some systems (e.g. KDE) critical notifications are not desirable as they will never expire.
+You can override notification urgency by setting the environment variable ``"AUTO_NOTIFY_URGENCY"`` to ``low``, ``normal``, or ``critical``.
+NOTE: This configuration option currently only works for Linux.
+
+::
+
+    # Force all notifications to have normal urgency
