-To use a custom domain for the SDK image:
-
-1. Add a custom domain for the Replicated registry in the Vendor Portal. See [Add a Custom Domain in the Vendor Portal](#add-domain) above.
+Because the SDK is located at the proxy registry domain, the SDK image is automatically pulled through the proxy registry during deployment.
 
-1. In the Replicated SDK Helm chart [`values.yaml`](https://github.com/replicatedhq/replicated-sdk/blob/main/chart/values.yaml#L33), update the `image.registry` field with the custom domain that you added.

+To use a custom domain for the SDK image:
 
-     ```yaml
-     # SDK Helm chart values.yaml
-     image:
-       # update image.registry with your custom domain
-       registry: example.your-domain.com
-       repository: "library/replicated-sdk-image"
-       tag: "1.0.0"

 With the Replicated proxy registry, each customer's unique license can grant proxy access to images in an external private registry.
