I think I really messed up

So I just got my first domain last night and was very excited to use Wordpress to give my blog a nice look and some good functionality. I wanted to change the Wordpress URL and changed it from “website.com” over to “website.com/wordpress” after I clicked “save changes” I have been thoroughly confused about where to go from there. I’ve been using Ajax to move the index.php file but I’m not sure where to move it or what to change on it.

I would really appreciate some help to get my first website up and running!
