+                    There are 2 kinds of URLs in WorkAdventure:
+                    <ul>
+                        <li>Public URLs are in the form https://play.workadventu.re/_/[instance]/[server]/[path to map]</li>
+                        <li>Private URLs (used in paid accounts) are in the form https://play.workadventu.re/@/[organization]/[world]/[map]</li>
+                    </ul>
+                    Assuming your JSON map is hosted at "https://example.com/my/map.json", then you can browse your map at "https://play.workadventu.re/_/global/example.com/my/map.json".
+                    Here, "global" is a name of an "instance" of your map. You can put anything instead of "global" here. People on the same instance of the map can see each others.
+                    If 2 users use 2 different instances, they are on the same map, but in 2 parallel universes. They cannot see each other.
