+#### Customizing the images used for wasmCloud host and NATS leaf
+
+If you would like to customize the registry or image that gets used to provision the wasmCloud hosts and the NATS leaf that runs alongside them, you can specify the following options in the above `WasmCloudHostConfig` CRD.
+
+For wasmCloud Host, use the `image` field:
+```
+apiVersion: k8s.wasmcloud.dev/v1alpha1
+kind: WasmCloudHostConfig
+metadata:
+  name: my-wasmcloud-cluster
+spec:
+  # other config options omitted
+  image: registry.example.com/wasmcloud:1.0.2
+```
+
+For the NATS leaf, use the `natsImageLeaf` field:
+```
+apiVersion: k8s.wasmcloud.dev/v1alpha1
+kind: WasmCloudHostConfig
+metadata:
+  name: my-wasmcloud-cluster
+spec:
+  # other config options omitted
+  natsLeafImage: registry.example.com/nats:2.10.16
+```
