Can anyone tell me which is accurate. I am following the provided install instructions at : http://www.buyscripts.in/vshare2-installation.html but after I go to mysite.com/install and follow direction I get conflicting directions

from http://www.buyscripts.in/vshare2-installation.html
8. Change permission of folder "include" and file "include/config.php" to 644

from mysite.com/install
Also chmod 755 include/config.php

Which is correct?
