Plugin "Gods", by kioferm, ¿how i change language?

Hi, my name is kioferm and i want help

I install the plugin "gods", after i want change the language but i dont can

This plugin say or have:
Languages & Custom God speak:

All the text for the Gods speech can be changed and customized to your needs.
You might want do adjust the tone of what a God say, expand what a God can say or even want a God to speak in another language!

All the God speech text files are found in /lang folder within the plugins folder and are by default automatically downloaded from my own server at http://www.doggycraft.dk.
(Note: To disable the download of language files, set the DownloadLanguageFile option to false in your config.yml.)
Simply use these file as templates for other languages or for adjusting the tone of voice for each God type
