+
+Enabling Pushover support is fairly easy, there are only two required parameters.
+
+Firstly you need to create a new Application (called LibreNMS, for example) in your account on the Pushover website (https://pushover.net/apps)
+
+Now copy your API Token/Key from the newly created Application and setup the transport in your config.php like:
+
+```php
+$config['alert']['transports']['pushover'][] = array(
+                                                    "appkey" => 'APPLICATIONAPIKEYGOESHERE',
+                                                    "userkey" => 'USERKEYGOESHERE',
+                                                    );
+```
+
+To modify the Critical alert sound, add the 'sound_critical' parameter, example:
+
+```php
+$config['alert']['transports']['pushover'][] = array(
+                                                    "appkey" => 'APPLICATIONAPIKEYGOESHERE',
+                                                    "userkey" => 'USERKEYGOESHERE',
+                                                    "sound_critical" => 'siren',
+                                                    );
+```

 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>`.
