+          CNAME:
+        A Canonical Name record is a resource used which defines that your domain name is an alias for another domain name.

+          three

+      %ol

+        %li
+          Add your own domain name to OSEM ( link to conference/custom_domain#create ) and select the conference it should belong to.
