+#### Set proxy within Netbox
+You can set the proxy for a device using the 'proxy' key in config context.
+```json
+{
+    "zabbix": {
+        "proxy": "yourawesomeproxy.local"
+    }
+}
+```
+Because of the posible amount of destruction when setting up Netbox but forgetting the proxy command, the sync works a bit different. By default everything is synced except in a situation where the Zabbix host has a proxy configured but nothing is configured in Netbox. To force deletion and a full sync, use the -p flag.
+
 #### Set interface parameters within Netbox
 When adding a new device, you can set the interface type with custom context.
 Due to Zabbix limitations of changing interface type with a linked template, changing the interface type from within Netbox is not supported and the script will generate an error.
