+   apiVersion: feast.dev/v1alpha1
+   kind: FeatureStore
+   metadata:
+     name: sample-feast
+     namespace: {{ include "feast-operator.namespace" . }}
+   spec:
+     feastProject: feast-test
+   EOF

+5. Check the FeatureStore status:
+   kubectl get featurestores -n {{ include "feast-operator.namespace" . }}
+
+{{- if .Values.metrics.enabled }}
+6. Metrics are available at:
+   kubectl get service -n {{ include "feast-operator.namespace" . }} {{ include "feast-operator.fullnameWithSuffix" (dict "root" . "suffix" "metrics") }}
