So either the intention is that you are expected to learn. Or you have somehow claimed that you do have the required knowledge for this project, and tricked the company.
Anyway - there is still zero complexities involved that someone with some skill using Google and some skill reading can't solve by spending a couple of days activelly looking for existing information.
