How to update script developed with Jetpack SDK

I would like to use Firefox standard add-on update to update my script developed with Jetpack SD开发者_如何学PythonK, but how?

cfx xpi --update-link http://example.com/addon/latest
        --update-url http://example.com/addon/update_rdf

Jetpack SDK generates regular XPI extensions, so the update situation is the same:

• If you host your extension on the addons.mozilla.org site, your users will update to the newest version of the extension automatically.
• Otherwise, see ungarida's answer and Extension Versioning, Update and Compatibility on MDC.
