Going live

Hi Word Press
As a beginner with very little knowledge I would be grateful for some help to make my website live. Each time I type in my domain name it goes straight to a screen like this.

Index of /
.cgi-bin/
.wp/
Apache Server at www……….. Port80

I then have to click on wp/ to visit my site. It is probably quite simple but I don’t want to alter anything in case I cause a problem; it has taken me a considerable time to set up the site.

Regards
