They give you the entire site built as a demo, with all the security already put in place. I know exactly what I post. When the PRUTUS site was first put up they left the source code out for anyone to look at and download. (which I did) The site was/is complete, which is why it's stated you can set up an exchange 'instantly'. From my DD, you can give the download to a monkey and expect a working site in less time...
