This is a call for help from any Unity user who wants to see the skin have the correct translation for their language.
I have recently gotten the current skin language resources added to Transifex. This should allow me to update the language files with the necessary translations a lot more regularly.
The project page can be found here on Transifex.
If you want to help out, you will need to register for a free account, and request to be added to the “Unity Skin for Kodi” project.
You can find some more information on Transifex on the Kodi Wiki here.
