Missing web.config

I have implemented this following the guide here https://technet.microsoft.com/en-us/library/mt488767.aspx but when I navigate to the http://pamsrv.priv.contoso.local:8090 IIS throws an error about no web.config. If I look in the directory using windows explorer, it is indeed missing. Is there a web.config file for the src directory that I can download or can you give me instructions on how to create one please?
thanks
