 To ensure NetBox Topology Views plugin is automatically re-installed during future upgrades, create a file named `local_requirements.txt` (if not already existing) in the NetBox root directory (alongside `requirements.txt`) and list the `netbox-topology-views` package:
 
 ```no-highlight
-echo netbox-topology-views >> local_requirements.txt
+echo netbox-topology-views >> /opt/netbox/local_requirements.txt

 Once installed, the plugin needs to be enabled in your `configuration.py`:
