 The following features that are available in kURL are not yet available in embedded cluster. Unless otherwise noted, some of these features might not be available at GA:
 
+* **Air gap**: Air gap support is not yet implemented for embedded cluster. We intend to implement support for air gap installations in the future.
+
 * **Backup and restore with Velero**: Velero is not yet installed as part of embedded cluster, so backup and restore is unavailable.
 
 * **Distributed storage with Rook**: OpenEBS is the only storage provider available today. We plan to introduce Rook as an alternative for multi-node clusters after GA.

-## Install in Air Gap Environments
-
-Air gap installations provide the same functionality as online (internet-connected) installations, including support for updates, adding nodes, and resetting nodes. The primary difference between online and air gap installations is that online installations pull images from the public internet, whereas air gap installations use a docker registry running within the cluster to store application images and infrastructure files.
-
-Air Gap installations require an `airgap` bundle unique to your application and the version of embedded cluster. You can generate and download `airgap` bundles from the **Release History** page for the target channel. For more information, see [Build and Download the Air Gap Bundle](/vendor/releases-sharing-license-install-script#air-gap-bundle).
-
-To install your application in an air gap environment:
-
-```
-sudo ./APP_SLUG install --license LICENSE_FILE --airgap-bundle AIRGAP_BUNDLE
-```
-Where:
-* `APP_SLUG` is the unique slug for the application.
-* `LICENSE_FILE` is the customer's license.
-* `AIRGAP_BUNDLE` is the path to the airgap bundle in your local directory.
