Add a new province?

[wisefather]

Hi

I havent been modding very long so plz bear with me. I really want to know how to add new cities and provinces, i tried following a guide on the internet but it was a bit advanced and my game kept crashing.
Basically, does anyone know of an easy to follow guide for adding new provinces?

Thanks, and sorry if this question has been asked before.

Don't know if this was the guide you tried following, but there's one on the forums located here.
