 Portal interfaces are available to sandboxed applications with the default
 filtered session bus access of Flatpak.
 
-Desktop portals appear under the bus name ``org.freedesktop.portal.Desktop``
-and the object path ``/org/freedesktop/portal/desktop`` on the session bus,
-unless specified otherwise.
-
-Apps running on the host system have access to a special interface for
-registering themselves with XDG Desktop Portal. Registering a host app with
-XDG Desktop Portal overwrites the automatic detection based on the
-`XDG cgroup pathname standardization for applications
-<https://systemd.io/DESKTOP_ENVIRONMENTS/#xdg-standardization-for-applications>`_.
-This might improve the user experience when the host app was launched in a way
-that doesn't follow the standard. See
-:doc:`org.freedesktop.host.portal.Registry <doc-org.freedesktop.host.portal.Registry>`

-All apps have access to the portals below:
+Unless otherwise specified, they appear under the bus name ``org.freedesktop.portal.Desktop``
+and the object path ``/org/freedesktop/portal/desktop`` on the session bus.
