+## Sample Grafana Dashboards
+
+This directory contains semi-generated dashboards for Grafana. It's using kubebuilder's 
+plugin introduced in [pr #2858](https://github.com/kubernetes-sigs/kubebuilder/pull/2858).
+
+In order to modify the custom metrics, change the config in [`custom-metrics/config.yaml`](./custom-metrics/config.yaml) and in project root run:
+
+```bash
+kubebuilder edit --plugins grafana.kubebuilder.io/v1-alpha
+```
