 # Application Installation and Uninstallation Process
 
+## Developers
+Developers can install and uninstall applications by running debug commands. For details, see [Multi-HAP Development, Debugging, Release, and Deployment Process](multi-hap-release-deployment.md#debugging).
 
-The OpenHarmony bundle manager service module provides APIs for installing, updating, and uninstalling applications. You can call these APIs when needed. After you release your application to the application market, users can install and uninstall it on their device.
