 ## Getting alerts
 
 As noted from the start, this document will only get you started with LibreNMS. A large number of additional configuration items exist, an extensive API (Application Programming Interface), an alerts system that provides a huge number of options for delivery, called "Transports", and much more. 
 
-This document does not contain any alert rules creation procedures. Instead, you will edit the built-in alert rule "Device Down! Due to no ICMP response"  that is pre-configured out of the box. For "Transports" use "Mail", which is just email. Know that you are not limited by this alert type.
