Help with phpGedView & Gallery2 module

Hello,
Can someone please help me get Gallery2 linked into my phpGedView install? The module install instructions are below but don't make any sense.
Thanks.

To install this module, download Gallery 2 from the official website (see below) and install it in the modules/gallery2 directory. Browse to the modules/gallery2 directory and follow the installation procedure. Once installed, put the gallery2.php file in the modules/ directory and (need help here--->>) replace modules/gallery2/index.php with the one provided. Go back to your PGV page and browse to module.php?mod=gallery2 . This should bring you to the Gallery 2 module.
