How to use the quickbooks addon?


I want to know about the purpose of quickbooks addon and how to use it in CS-Cart of version 2.1.1. I tried to get an idea about this addon in the knowledge base but I didn’t find this addon in the addons section of the knowledge base for a version of 2.x.

Can anyone please help me to clarify my doubts regarding the quickbooks addon or suggest me where can I get the info about that addon.
