+### Priority
+
+Add a priority (optional) associated with your monitors. Values range from P1 through P5, with P1 being the highest priority and the P5 being the lowest.
+To override the monitor priority in the notification message, use `{{override_priority 'Pi'}}` where `Pi` is between P1 and P5.
+
+For example, you can set different priorities for `alert` and `warning` notifications:
+
+```
+{{#is_alert}}
+{{override_priority 'P1'}}
+ ...
+{{/is_alert}}
+{{#is_warning}}
+{{override_priority 'P4'}}
+...
+{{/is_warning}}
+```
