+Action frontend arguments names
+-------------------------------
+
+Most of the `launch_ros` Python actions (:class:`launch_ros.actions`) are `available through the XML and YAML frontends <https://docs.ros.org/en/rolling/How-To-Guides/Launch-file-different-formats.html>`_.
+The name of the action arguments might vary between the underlying Python implementation and the frontends.
+
+:class:`launch_ros.actions.Node`
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Action frontend name: ``node``.

+# The python interpreter that executes this conf.py file will not have this
+# package's modules in the system path which will lead to import failures when
+# running sphinx-autodoc. As a workaround, the sphinx_builder.py script in
+# rosdoc2 will copy this package's modules along with this conf.py into a folder
+# with the same name of this package within the docs_build directory.
+# Hence we add the parent folder to the system path so that the modules from
+# this package can be imported.
