Can you be more specific? What kind of help are you looking for?
Hi, could you be more specific? Would you like to build an old website with Adobe XD or copy an artboard from an old project to a new one?
The best way is to start with scratch in Adobe Xd. Make screen shot from that site import bitmap into Xd and start building your website. There isn't any option to load HTML file into XD. For that purpose you can use Dreamweaver after downloading full HTML version in browser.
