+# Crunchy Postgres Operator
+
+This chart is used to deploy [Crunchy Postgres Operator](https://access.crunchydata.com/documentation/postgres-operator/latest) (PGO).
+
+This chart is just a copy of [their official chart](https://github.com/CrunchyData/postgres-operator-examples/tree/main/helm/install). It is only copied here so that it is published in a Helm repository (the official chart is not published anywhere and requires a manual git clone).
+
+Docs:
+
+<https://access.crunchydata.com/documentation/postgres-operator/latest/>
+
+Examples Repo:
+
+<https://github.com/CrunchyData/postgres-operator-examples>
+
+Original source of this chart:
+
+<https://github.com/CrunchyData/postgres-operator-examples/tree/main/helm/postgres>
+
+## Usage
+
+Add this chart repository if you haven't already:
+
+```sh
+helm repo add jshimko https://jshimko.github.io/helm-charts
+helm repo update
+```
+
+To install PGO in your cluster:
+
+```sh
+helm install pgo -n pgo jshimko/pgo
+```
+
+Now you can deploy a `PostgresCluster` in any namespace:
+
+```sh
+helm install my-pg-cluster -n my-namespace -f my-values.yaml jshimko/postgrescluster
+```
+
+See the [postgrescluster chart](../postgrescluster) for more info.
