+This repository contains a collection of examples for deploying, operating, and maintaining Postgres clusters using PGO, the Postgres Operator from Crunchy Data as part of [Crunchy Postgres for Kubernetes](https://www.crunchydata.com/products/crunchy-postgresql-for-kubernetes). Using these examples assumes that you already have PGO running. The kustomize installer for PGO can be found in the [postgres-operator](https://github.com/CrunchyData/postgres-operator) repo. The PGO helm installer can be [installed via the OCI registry](https://access.crunchydata.com/documentation/postgres-operator/latest/installation/helm#installing-directly-from-the-registry).
 
 The use of these examples with PGO and other container images (aside from those provided by Crunchy Data) will require modifications of the examples.
