Using EpiNum2Words for India

I was able to follow some other posts to initially get this function to work, however I am not finding any information on the parameters it uses. I need to get Numbers to words for currency INR (Indian Rupee) where it would do something like below.
336,000.00 shown as Rupees Three Lakhs and Thirty Six Thousand Only

Does anyone know where I can get more information on this?

Greatly appreciate anyone’s help.
