-## About Private Registries
+## Overview
 
-Using a private registry lets you create a custom image pipeline. Any proprietary configurations that you make to the application are shared only with the groups that you allow access, such as your team or organization. You also have control over the storage location, logging messages, load balancing requests, and other configuration options.
+You can push images to your own image registry. Any proprietary configurations that you make to the application are shared only with the groups that you allow access, such as your team or organization. This gives you control over the storage location, logging messages, load balancing requests, and other configuration options.

For kURL clusters, if the Replicated kURL installer spec includes the kURL Registry add-on, then the built-in kURL registry is used to host the application images. For more information, see [Working with the kURL Image Registry](image-registry-kurl).
