-# CYBERTEC PG Operator
+# CYBERTEC PG Operator (CPO)
 
-CPO (CYBERTEC PG Operator) allows you to create and run PostgreSQL clusters on Kubernetes.
+**The CYBERTEC PG Operator (CPO)** is a powerful Kubernetes operator that dramatically simplifies the creation and management of highly available **PostgreSQL clusters**. 
+Fully integrated with GitOps/CI/CD workflows and infrastructure-as-code principles, CPO enables consistent, secure and automated database provisioning - **without direct access to the Kubernetes API**.
 
-The operator reduces your efforts and simplifies the administration of your PostgreSQL clusters so that you can concentrate on other things.

+![CYBERTEC Logo](docs/diagrams/cpo_logo.svg)
 
-The Postgres Operator delivers an easy to run highly-available [PostgreSQL](https://www.postgresql.org/)
-clusters on Kubernetes (K8s) powered by [Patroni](https://github.com/zalando/patroni).
-It is configured only through Postgres manifests (CRDs) to ease integration into automated CI/CD
-pipelines with no access to Kubernetes API directly, promoting infrastructure as code vs manual operations.

+## Highlights
+
+- **Completely declarative configuration** via custom resources
+- Highly available PostgreSQL clusters** with [Patroni](https://github.com/zalando/patroni)
+- Seamless integration into CI/CD pipelines** (e.g. ArgoCD, Flux)
+- Compatible with OpenShift**
+- **Support for cloud & on-prem environments**
