+# About CloudNativePG
+
+[CloudNativePG](https://cloudnative-pg.io) is an open-source Kubernetes
+Operator specifically designed for PostgreSQL workloads. It manages the entire
+lifecycle of a PostgreSQL cluster, including bootstrapping, configuration, high
+availability, connection routing, and comprehensive backup and disaster
+recovery mechanisms. By leveraging PostgreSQL's native streaming replication,
+CloudNativePG efficiently distributes data across pods, nodes, and zones using
+standard Kubernetes patterns, enabling seamless scaling of replicas in a
+Kubernetes-native manner. Originally developed and supported by
+[EDB](https://www.enterprisedb.com/), CloudNativePG is a
+[CNCF Sandbox project](https://www.cncf.io/projects/cloudnativepg/)
+and the sole PostgreSQL operator in this category.
