 For **minikube users**:
 > **NOTE**: If you're running Docker Desktop or Minikube with a local k8s cluster, the above step to use your host IP
 > might not work. Luckily, you can port-forward a service port to your localhost using the following command to be able to
-> access the UI either via `http://localhost` or `http://<HOST_IP>` (you require sudo to run this command in order to bind
-> to a privileged port).
+> access the UI either via `http://localhost:8088` or `http://<HOST_IP>:8088` (If you want to use privileged ports such as 80, you need to run this command with sudo to bind to the privileged port).
 
 ```bash
 kubectl port-forward svc/ui --address=0.0.0.0 8088:8088
