+----------------------
+
+If the ``DomainParticipant``'s :ref:`discovery protocol<discovery_protocol>` is set to |SIMPLE|,
+and ``ROS_SUPER_CLIENT`` is set to TRUE, the participant is automatically promoted to a |SUPER_CLIENT|.
+
+.. important::
+    This environment variable is meant to be used in combination with ``ROS_DISCOVERY_SERVER`` to promote a participant from |SIMPLE| to |SUPER_CLIENT|.
+    The participant will have the *servers* list defined in ``ROS_DISCOVERY_SERVER``.
+
+The possible values are: **TRUE**, **true**, **True**, **1**, **FALSE**, **false**, **False**, **0**.
+
+.. important::
+    If the variable is not set, the default behavior of Fast DDS is equivalent to the case in which the variable is set to false.
+
+The following example shows how to set the environment variable to true.
