The process of installation does not require any specific skills. You just fill in app settings (such as, administrator credentials), and Panel installs the app for you. Further app management is also facilitated as you can update or remove apps directly in Panel. Moreover, you can access some functions that apps reveal to the Control Panel (without the need to log in to an app). For example, you can add SugarCRM user account right from your Control Panel. Such app functionality is a service provided by the app.
After you install an app, grant other auxiliary user accounts access to it if you want them to be able to use the app.
