I have the codes for this web page that I want to use as my home page

But how do I use it for my homepage?

I have this free template, which I would like to use from this site:
http://www.freewebsitetemplates.com/template2.php
http://www.freewebsitetemplates.com/preview/architecture2/

I downloaded the following, but how do I use them to make it my forum homepage?



But what do I do with it?

Thanks.
