Installing GAUSS applications files

Hi, I have a GAUSS application that contains four files (doc, examples, lib, and src). According to https://www.aptech.com/support/installation/installing-applications-for-gauss-for-windows/ it says that we have to place each of those files (without mentioning the doc file) in Users/YourUserName/gauss11 in a Mac. In my gauss version folder I already have src, lib, and examples folders. Am I supposed to replace them with the ones contained in the GAUSS application? Please advise. Thanks!!
