I'm able to reach the demo from Windows, but

The next part of the tutorial is to make a new site map. I’ve a Samba share with my raspberry pi, but how do I look at configurations & how do I create a new sitemap?

Thanks!

One option is to use the designer if you have already a samba share
Installing the openHAB designer
… and take a look at the sitemap wiki.

Thank you!

I’ll give that a try later. Do I start the under the title, Installing the openHAB designer (optional)?
