How to integrate Ratings and Review through SDKBOX

I want to integrate ratings and review functionality in my cocos2d-x project using SDKBOX.I have successfully installed plugin using terminal.
Now, which method and functions I have to call to make it work in the project and where should I have to put this method??
I have downloaded plugin from this site
http://cocos2d-x.org/sdkbox/ratings_reviews
But here they haven’t explain further process for integration…

Normally a documentation link should be opened after installation
http://sdkbox-doc.github.io/en/plugins/review/v3-cpp/

We also provide sample for review
https://github.com/chukong/sdkbox-review-sample

Thanks, It is very helpful to get an idea of integration.
