A Dashboard is the administrative panel of your translation tool. Administrators can access these special pages in order to configure their own translators and have an outlook on what is going on under their brand-account.
A string translation is the simplest and most common type of translations. A string alias can contain all the content you need.
An Array translation is a special structure for your translations that are related to the same object. An array is the ideal when you need to create translations that are related to something in common. For example, you can create one array with the months-name instead of 12 string translations.
