When Knot Resolver is started using Systemd (see section
:ref:`quickstart-startup`) it creates a control socket in path
-``/run/knot-resolver/control/$SYSTEMD_INSTANCE``. Connection to the socket can
+``/run/knot-resolver/control/$ID``. Connection to the socket can
be made from command line using e.g. ``netcat`` or ``socat``:
.. code-block:: bash
4.x to 5.x
