+The operator installs and updates its own CustomResourceDefinitions when it starts, so the chart
+does not ship them. They appear shortly after the pod becomes ready.
+{{- else }}
+WARNING: maintenance.customResourceDefinitions.maintain is false, so this operator will not install
+its CustomResourceDefinitions and the chart does not ship them either. Apply them yourself before
+creating any resources managed by this operator, otherwise the API server will reject them.
