+# Prometheus Stack CRDs
+
+CRDs for Prometheus Stack.
+Thay can be installed in an empty cluster so that
+
+- ServiceMonitors
+- PodMonitors
+- PrometheusRules
+
+can be created by other charts without raising errors if Prometheus Stack is not yet installed.
+
+## Install
+
+### Helm
+
+```shell
+helm upgrade  --wprometheus-crds-navarcosait --install navarcos/prometheus-crds-navarcos
+```
+
+## Chart Update
+
+Prometheus stack CRDs are copied from the original chart (prometheus-stack-navarcos).
