Translation Module
The translation module allows you to add translations to the app. When a user opens the app they choose their preferred language and the app will load content from the set up translation module — so each module Calendar, Newsletters, Contact, Alerts, etc is set up in two or more languages with a place to add English content and its translation. 
The backend has the translations preloaded — for all your headings and instructions, etc, and you have access to these translations in case you wish to alter any of them.
The buttons on the homepage will also be translated and I will gather these from you for our designer to add.
