You can add the app directly to your facebook page using this link:
https://www.facebook.com/dialog/pagetab?app_id=437951106265166&next=http://apps.facebook.com/asksumo
The content will load from Mozilla Hispano server and will be always updated with all the supported locales and improvements.
If you want to request a new localization, you can do it from the 'create a language' feature and then localize asksumo online from the resource at transifex (you will need to be logged in)
Once you finish, please open a new issue here with "Add YourLocaleName (xx-XX)" as title asking for addition.
(Keep in mind you need to localize SUMO hot articles in your language in order to be fetched by this app.)
You can also create a new Facebook app and host the code on your own, but if you want to have it updated we recommend to add our already created app
