multi language website

Hi, I have been using this theme for several months and it works really well. Thank you. Lately, our company is trying to expand the market and would like to have two language of the website. I'm imagining having "English | Local language" menu on the top, and when clicking each language, then the contents will be adjusted to those languages. Do you have any idea on how to easily do that by using Intuitive Pro? Any comments are appreciated. Thank you in advance.
