 ## Overview
 This chart is an All-in-one solution to start monitoring kubernetes cluster.
-It installs multiple dependency charts like [grafana](https://github.com/grafana/helm-charts/tree/main/charts/grafana), [node-exporter](https://github.com/prometheus-community/helm-charts/tree/main/charts/prometheus-node-exporter), [kube-state-metrics](https://github.com/kubernetes/kube-state-metrics/tree/master/charts/kube-state-metrics) and [victoria-metrics-operator](https://github.com/VictoriaMetrics/helm-charts/tree/master/charts/victoria-metrics-operator).

 By default, the operator [converts all existing prometheus-operator API objects](https://docs.victoriametrics.com/operator/quick-start.html#migration-from-prometheus-operator-objects) into corresponding VictoriaMetrics Operator objects.
