+
+Enabling PagerDuty transports is almost as easy as enabling email-transports.
+
+All you need is to create a Service with type Generic API on your PagerDuty dashboard.
+
+Now copy your API-Key from the newly created Service and setup the transport like:
+
+```php
+$config['alert']['transports']['pagerduty'] = 'MYAPIKEYGOESHERE';
+```
+
+That's it!

 Entities as described earlier are based on the table and column names within the database, if you are ensure of what the entity is you want then have a browse around inside MySQL using `show tables` and `desc <tablename>`.
