In essence the directions between XP and any other OS are identical.
You have to have a webserver on the machine. It has to run have PHP 4.3 (or better) and MySQL 4.1 (or better) installed. You have to setup a mysql user for the site.
You would then put the contents of the archive in the folder you selected for the site, you would open a web browser and go through the web based setup.
I do not believe that there are any official installation docs specifically for your OS.
