+## OCI Registry
+
+This repository comes with an officially supported OCI registry. For usage with
+FluxCD, you can use the following snippet:
+
+```yaml
+---
+apiVersion: source.toolkit.fluxcd.io/v1beta2
+kind: OCIRepository
+metadata:
+  name: kustomizations
+  namespace: flux-system
+spec:
+  interval: 12h
+  ref:
+    semver: '>=0.1.0'
+  url: oci://ghcr.io/meysam81/kustomizations
+---
+apiVersion: kustomize.toolkit.fluxcd.io/v1
+kind: Kustomization
+metadata:
+  name: echo-server
+  namespace: flux-system
+spec:
+  interval: 1h
+  path: ./echo-server/overlays/default
+  prune: true
+  retryInterval: 2m
+  sourceRef:
+    kind: OCIRepository
+    name: kustomizations
+  targetNamespace: default
+  timeout: 5m
+  wait: true
+```
