 * **description** : The complete description of the app. You can make it as detailed as you feel it should be. Only `en` is required right now, but you can translate the description by prepending the locale prefix.

 * **multi_instance** : This defines your app's ability to be installed multiple times. When YunoHost tries to install a second instance of your app, it will replace the `id` in your scripts by an `id__2`. It means that, if you want to be `multi_instance`, you have to put all the identifiers in the scripts.
