-Vulcanexus integrates `ROS 2 Monitor <https://fast-dds-monitor.readthedocs.io/en/latest/>`_, which is a useful tool for monitoring and studying a ROS 2 network as ROS 2 relies on the `DDS specification <https://www.omg.org/spec/DDS/1.4/About-DDS/>`_ to communicate the different nodes.
-The automatic discovery of entities in a local network enables to easily identify the different running Participants, their Endpoints, the Topics that each of them is using, and even the network interfaces they are employing to communicate with one another.
-Additionally, it is possible to receive statistical data from every endpoint in the network leveraging the `ROS 2 Statistics Module <https://fast-dds.docs.eprosima.com/en/latest/fastdds/statistics/statistics.html>`_.
-This data is very useful to analyze the DDS network performance and seek possible communication problems in it.
+Vulcanexus integrates the `ROS 2 Monitor <https://fast-dds-monitor.readthedocs.io/en/latest/>`_, a powerful tool for monitoring and studying ROS 2 networks. Since ROS 2 relies on the `DDS specification <https://www.omg.org/spec/DDS/1.4/About-DDS/>`_ for communication between nodes, this tool simplifies the process of observing network activity..
+With automatic entity discovery within a local network, users can easily identify active Participants, their Endpoints, the Topics they utilize, and even the network interfaces used for communication.

 Alias
 ^^^^^
 
 Participants in ROS 2 are named :code:`/` by default.
 In order to differentiate them, it is possible to change the Participant's aliases within the *ROS 2 Monitor*.
-In this case, the :code:`vulcanexus-jazzy-talker` Participant would be the one with a writer, and the :code:`vulcanexus-jazzy-listener` Participant would be the one with a reader.
+In this case, the :code:`talker` Participant would be the one with a :code:`chatter` writer, and the :code:`listener` Participant would be the one with a :code:`chatter` reader.
