Cafu Engine

I'm so confused on how to set Cafu up-

It said to unzip the file from the website (which I believe is named cafu-cafu-d88e4483fb52). I did do that from WinRar, and now I don't know what to do next. Any help is appreciated, thanks in advance.

To be a little more precise- there's no exe file.

Nvm...I dnwoloaded the wrong thing
