Anyone good with Wordpress/Web Hosting stuff?

So I'm in a need of a little help here. I'm creating a site for myself and I just want to use Wordpress. The problem is I can't get wordpress to show up as my main page such as www.websitename.com I can only get it to show up when I use www.websitename.com/wordpress or using a similar name such as /index or/content. I'm using 1and1 Hosting and I feel it's just a simple name change or something but I've tried everything I know. I'm also using Filezilla to upload files if that matters. I hope this makes sense but any help is appreciated.
