 ## Overview
 
 When an air gap bundle is built for a release containing an Embedded Cluster Config, both an application air gap bundle and an Embedded Cluster air gap bundle are built. The application air gap bundle can be used for air gap installations with Replicated kURL or with Replicated KOTS in an existing cluster. The Embedded Cluster air gap bundle is used for air gap installations with Embedded Cluster.
