Support System 1.5.5 does not have install instructions

I just unzipped the Support-System-1.5.5.zip (file dated: 11/30/2010 11:54pm) and it does not have installation instructions.

the /incsub-support folder in the zip contains:
/languages
/js
/images
/css
/.komodotools
/readme.txt (which seems to be a change log)
incsub-support.php

i've checked all the folders and there are no instructions with the package.
