Thank You very much for your precious feedback. We have noted it and will definitely improve on it.
The instructions are pure technical currently. We will add comments and proper recommendations to make it seamless with the installation process.
We will also add support for the install from web option in Joomla.
We really appreciate that you allowed us your genuine feedbacks and time.
Team Ready Bytes.
I HIGHLY recommend this extension to everyone who wishes to integrate Facebook with their site.
