Directing users directly to my blog but using domain adress

I have a domain at https://www.patrickwalkerfoto.com. I have been using my main web site (built from scratch with Web Plus x4) at this adress and want to continue using this adress as it is on my business cards.

I have also a blog at /pwblog which is refered to in my menu in my main site.

Now I have made some important changes to my blog (started using WP), and it has beeen built from a simple blog to a full website with blog.

I want this wp site(at /pwblog) to become my main web site when users click https://www.patrickwalkerfoto.com.

How do I make this happen ?

Thanks
Patrick
