Site already on WordPress and I just registered for Host Gator

Hi, I am new to wordpress and to be honest, I know absolutely nothing. I am just learning as I go. I set up a site on WordPress and bought a hosting package after the fact so I can add some plugins to my existing site. My question is: now that I have set up my site and signed up for a hosting package at Host Gator……what do I do now? Thanks to whoever takes the time to answer this question, hopefully it is an easy one!
