About Language Skins

A regular skin controls the interface that users see for online outputs. They are stored in the Skins folder of the Project Organizer. By default, the text in these skins is in English, and they are used not only for editing text but also to control the look of the skin in the output. See About Skins.

On the other hand, a language skin can be used to display the interface in a specific language for online outputs. Language skins also control some text-based items, like cross-reference links. Language skins hold only text used for the output; they do not control the look of the output. To control that, you must also use a regular skin.
