How to install a second language

This is my first multi-language site so I have some basic questions that I can not find answers on the forum.
I have installed the Joomla es-ES translation pack and also the VM translation pack. Is there also a Spanish translation for the template (es-ES.tpl_gk_storefront.ini) or do I need to create one myself? If I need to create it, then how many files do I need to create - is there one for each module - NewsShowPro, ImageShow, etc.?

Hola,
We do not have ES translation for template, so you have to build your own language file based on ours.

And yes, in theory you have to translate also all modules ini. language files,
but do not worry translate only selected strings - from front-end only.
