 ### Configure Access to Multiple Clusters
 
+> **Attention:** When kubenav runs inside a Kubernetes cluster with the `--kubeconfig` flag and the Prometheus plugin enabled (`--plugin.prometheus.enabled`) it will only use the Prometheus instance, which is running in the same cluster.
+
 The deployment shown in this repository deploys kubenav with the `--incluster` flag. This means kubenav has only access to the cluster were it is deployed in. To deploy kubenav with access to multiple cluster you have to mount a Kubeconfig file into the kubenav container and add the `--kubeconfig` flag.
 
 The following example shows the changes you have to made to the `deployment.yaml` file to access multiple clusters from the same kubenav instance:
