hmmmm... git clone it somewhere then setup config.php in www from config-dist.php

if you cant do that without assistance at this point, dont bother touching this code yet.

The only things i will tell you are this:

1. sqlite only is supported at this time
2. $db_name is the location of the db in config.php
3. db must be web-user writable

If you need more then that, then wait for a more useable install, its not that far off really
