Where do I put the files on the main domain?

I have configured my ehcp installation and now when I goto my website domain name it takes me to the default page.
See this: awesome-techs.net

My nameservers are ns.1awesome-techs.net and ns2.awesome-techs.net

Now where do I put the files so that if any one comes to awesome-techs.net he sees the my index.html instead of the default one?
