Due to Siren's implementation, if a user's application is not published on the US appstore Siren will fail to find the application. To resolve this we add support for a config variable SirenCountryCode which will configure Siren to search for your application in the specified appstore region.
It may also be useful to provide config variables for some if not all of the siren rules to allow further customization whilst using this plugin.
