Added. Plus added the link to the site page.

I really think that's a nice addition! How about sharing tasks just like we did the Tsite intro texts. I volunteer to find some for Jordan and Egypt sites as I visited them all a few months ago. Will also check Canadian ones as I know most of them well.

Sceilg Mhichil has been done by Digits

We are also working on adding some more core zones, including Sceilg Mhichil (there now! look at the blue zone, not on the confusing green one that is the wider nature reserve as indicated on the OSM map) and many of the US sites as once mapped by meltwaterfalls. They need some slight refactoring but will appear soon.

I also have updated the general instructions in this post.

Digitis did https://www.worldheritagesite.org/list/bru-na-boinne/

I have converted my infamous WHS Walking Map of Willemstad into a dozen POIs in the core zone of Willemstad, Curacao.
