The documentation shows how to export "Mobile Application" in chapter 8.3.7. It says "ready-to-sign applications", but I'd be good to show, what can the user then do with the exported application, as readers of this guide might not be aware of how native packages work.

When export is made for iOS, the output is a single .app package. For Android, it's an .apk archive. It should be made clear to user what those packages are and possibly link to official documentation on given topic if it exists.
