+# Kubernetes Operator for Nessie
+
+This module is a Kubernetes Operator for Nessie.
+
+**WARNING: This is a work in progress and is not ready for production use.**
+
+The operator is designed to manage the lifecycle of Nessie instances in a Kubernetes cluster.
+
+This project was bootstrapped using [Operator SDK]:
+
+```bash
+operator-sdk init --plugins=quarkus --domain=projectnessie.org --project-name=nessie-operator
+operator-sdk create api --plugins=quarkus --group nessie --version=v1alpha1 --kind=Nessie
+operator-sdk create api --plugins=quarkus --group nessie --version=v1alpha1 --kind=NessieGc
+```
