+# Mirroring with Cluster API
+
+## Identifying Images To Mirror
+
+You can use [`clusterctl`](https://cluster-api.sigs.k8s.io/clusterctl/overview.html) to list the images used by Cluster API and the Cluster API provider in use:
+```
+clusterctl init list-images --infrastructure <infrastructure-provider>
+```
+For more details see: 
+https://cluster-api.sigs.k8s.io/clusterctl/commands/additional-commands.html#clusterctl-init-list-images
+
+## Mirroring Images
+
+See our general list of [mirroring options](./README.md#Mirroring-Images)
+
+## Using Mirrored Images
+
+To use Cluster API with mirrored images, you can configure clusterctl to use image overrides.
+
+For more details see:
