How to update Nginx in Debian to current ver?

I did a fresh install of nginx on a debian server.

When I check the version of nginx, it reports 0.7.67

However, the current stable version of Nginx is 1.0.5 from what I have read.

How can I update my Nginx whilst leaving my server operational?

I am a relative newb, so please do not make answers too complex.

Never mind. I think I have managed to do it. I used the dotdeb.org repository and simply installed nginx again over the top of the old one. It seemed to manage ok.

you should update data from repository to get latest versions. in aptitiude, press u
