Hope am in the right place to post this as first time posting

Latest version of Zencart installed
Site is a brand new website and only just finished propagating the domain
Only addon installed is a template
Have also only changed the header on the template
No problems as such with zencart the site is running well

But when installing zencart I followed the instructions as its my first time installing it and put it in a folder called catalog

What I want to do is have zencart as my homepage but havent a clue now how to do that

I have been reading on the forum for quite a bit before joining and cant find an answer to how to get it to work this way

Any help is appreciated
