I want to add multilanguage(rus,..) support in social engine site . I already added rus folder in directory application/languages.

I know that Social Engine written with Zend framework(wich I don't know) and maybe I must change or add part of code there(maybe within Zend_Translate_Adapter_Csv and Zend_Translate_Adapter classes)?I have read http://framework.zend.com/manual/en/zend.translate.sourcecreation.html document,but I don't know where I must add it.
Can someone get me some advice?
