+**Notification Urgency Level**
+
+By default non zero exit codes lead to critical notifications.
+On some systems (KDE) critical notifications 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
