+  - Or follow our [tutorial](tutorials/00-install-kubernetes-env.md)
+
+After that you can run:
+
 ```bash
 sudo bash install.sh
 ```

 Forward the Grafana dashboard port to the local node-port
 
 ```bash
 sudo kubectl --namespace monitoring port-forward svc/kube-prom-stack-grafana 3000:80 --address 0.0.0.0
 ```

+```bash
+sudo kubectl --namespace monitoring port-forward prometheus-kube-prom-stack-kube-prome-prometheus-0 9090:9090
