CS Cart as home page

I need to resolve the index.php cs-cart hp to my site home page. This is my first time working with CS-Cart so any help is appreciated. I created a directory named shop and installed it in there. This should be easy but I don’t see how to go about it.

Thanks for any help.

I followed the instructions and installed it in a different directory but now it looks like I have to re-install it because I want the cs-cart homepage to come up the regular site url.

Is this correct? I thought I could use another directory like MediWiki does and just change a couple of things.
