+### Use-case: Propagate a private registry secret to all namespaces
+
+The second use-case for this operator is to take an authentication token which is required to pull images from a private registry, and to make sure it's available and configured for each and every namespace.
+
+For example, if you were running a multi-tenant service, where customers had their own namespaces, and every Pod was pulled from a common private registry. You could use this operator to automate what would otherwise be a manual and error-prone process.
 
-The primary reason for creating this operator, is to make it easier for users of Kubernetes to consume images from the Docker Hub after [recent pricing and rate-limiting changes](https://www.docker.com/pricing) were brought in, an authenticated account is now required to pull images.
