Modified launch files tutorial, added a note to the README. - #1008
Launch File tutorial
Added explanations for the member function of MoveItConfigsBuilder.
Added note about launch nodes for custom .cpp files.
Having made these suggestions, I now wonder if I am being too verbose and just cluttering up the documentation when someone wanting to learn more can do what I did and read the source code. So maybe the launch file tutorial should remain unchanged.
README
Added a note that building MoveIt can be skipped if only adding explanations, note any executable code. This is mostly addressing my own pain of building MoveIt (about a 3-4 hour process) and I could see it stopping someone from adding a few helpful comments.
Please explain the changes you made, including a reference to the related issue if applicable

Summary by CodeRabbit
Documentation
Expanded the MoveIt C++ tutorial with launch-file, node, parameter, and build-configuration guidance.
Updated the configuration guide with robot description, controller, planning-scene-monitor, and planning-pipeline options, including how planner defaults are selected.
Clarified how to define a Move Group Interface node and added guidance for launching a custom executable.
As an aside, I would have liked to add more about '.planning_scene_monitor()' regarding when you need to set its parameters to be true, but I haven't found good explanations regarding common uses cases. If you can point me in the direction of where to learn more, I would be happy to add that info to the tutorial.
The reason will be displayed to describe this comment to others. Learn more.
Thank you for getting this started!
My first response here is that the information being added is largely already available in other tutorials. I would recommend reading through some of the other pages I've linked in the comments, and seeing if there's a better way to take advantage of cross-linking doc pages, but keeping each individual page focused on a specific subset of topics.
Ok, I'll make those edits. Do you know if any of the tutorials discuss the parameters for .planning_scene_monitor()? It seems lacking from the moveit_configuration_tutorial.

If I wanted to cross link to the CMakeLists.txt file in the root moveit2_tutorials directory, how would I do that?
:doc:moveit2_tutorials/CMakeLists.txt (the backticks turn "moveit2_tutorials/CMakeLists.txt" into inline code)
doesn't seem to work. I assume that is because :doc: only works for files in the doc folder? I also assume that it would be poor form to directly link to "https://github.com/moveit/moveit2_tutorials/blob/main/CMakeLists.txt"

I believe you can use :codedir: -- you can see the definitions here, and also search for similar usages in the .rst files in these docs.
There are other handy ones for linking to e.g. source code in the MoveIt 2 repo, etc.
It does look that way -- maybe instead of linking to the existing repo's CMakeLists.txt, you can just copy-paste a small relevant snippet of what you intend to show?
I assume this is just the compilation of a specific executable given source files?
Updated the tutorial:
Moved most of the config specific edits to the configuration tutorial.
Aside from adding a link in the launch tutorial to the moveit_cpp tutorial, the launch tutorial went back to how it was.
Added the CMakeLists.txt code and explications to the moveit_cpp tutorial.
``PUBLIC`` makes the include directory available to targets that depend on ``moveit_cpp_tutorial``.
``ament_target_dependencies`` specifies dependencies for the moveit_cpp_tutorial executable.
``${THIS_PACKAGE_INCLUDE_DEPENDS}`` is a variable defined in the ``moveit2_tutorials`` root directory's CMakeLists.txt file, which list common dependencies used in moveit2_tutorials.
``.robot_description`` can optionally take a file path to ``robot_name.urdf`` and/or assign a dictionary of argument mappings that are passed to the robot's urdf.xacro file.
The file path to ``robot_name.urdf`` must be relative to your robot package, so if your robot package is ``/robot_package`` and the urdf (or urdf xacro) file is ``robot_package/config/robot_name.urdf``
you would pass ``.robot_description(filepath="config/robot_name.urdf")``.
If you don't provide a file path, but you do give ``MoveItConfigsBuilder`` a robot name (see above paragraph), MoveIt will look for ``robot_package/config/robot_name.urdf``.
``.trajectory_execution`` loads trajectory execution and MoveIt controller manager's parameters from an optionally provided file path.
If a file path isn't given, MoveIt looks for files in the package's ``config`` folder for files ending with ``controllers.yaml``.
``.planning_scene_monitor`` allows you to set various parameters about what scene information is published and how often is it published.
``.planning_pipelines`` allows to you to list the names of the planners you want available to be used by your robot.
If you opt to not list pipelines, as in ``.planning_pipelines()``, MoveIt will look in the config folder of your package for files that end with "_planning.yaml".
Additionally, if no pipelines are listed, MoveIt will load a set of planners from its own library - this can be disabled adding ``load_all=False`` as an argument to ``.planning_pipelines``.
Listing the planner names specifiies which planners MoveIt should load; again these should be in your config folder.
MoveIt will also pick one of your planners to be the default planner.
If OMPL is one of your planners, it will be the default planner unless you set ``default_planning_pipeline`` to your desired default planner as in

…mber funtions.
Added note to Launch FIles tutorial about nodes for custom cpp files.
Added note to README.md that building Moveit is not needed if only adding explinations, not exectuable code. This is mostly addressing the pain I feel of building MoveIt (3-4 hours on my laptop). Maybe I am an anomily.
The tutorials update MoveIt configuration examples and describe configuration options, Move Group Interface node setup, and custom executable creation and launch guidance.
Changes: MoveIt tutorial documentation
Layer / File(s)
Summary
Configuration example and builder options doc/how_to_guides/moveit_configuration/moveit_configuration_tutorial.rst
The example now uses a Kinova Gen3 configuration package and lists controller, planning-scene-monitor, and planning-pipeline settings. The guide describes builder arguments, configuration discovery, and planner selection.
Move Group Interface and custom executable guidance doc/how_to_guides/moveit_launch_files/moveit_launch_files_tutorial.rst, doc/examples/moveit_cpp/moveitcpp_tutorial.rst
The launch guide describes defining the Move Group Interface node and links to custom executable guidance. The C++ tutorial documents its launch file, node parameters, and CMake setup.
This PR only changes tutorial text, but several examples would fail or mislead when copied: a wrong constructor call, a wrong keyword argument, a mis-indented launch block, and a CMake snippet that does not match the real file. A doc link is also broken. Fix these before merging so readers can follow the tutorials, but no production risk is involved.

Explanation
The title says the launch files tutorial was modified and a README note was added. The raw summary shows the launch files tutorial changes (Move Group Interface node wording, custom executable section, blank line), and the objectives mention a README note about building MoveIt being unnecessary for explanation-only changes. The title names the main change and a secondary change. It is somewhat generic ("Modified") and does not say what the modification achieves, but it relates to the changeset and does not mislead.

keyword instead of filepath, so the documented launch call runs without a
TypeError.
- Around line 203-204: Correct the MoveItConfigsBuilder constructor examples to
match its required robot_name argument and package lookup behavior. Update both
examples to show how to provide a custom package name using the appropriate
arguments, rather than implying that package_name alone is valid or that a
single positional robot_name names the package directly.
- Line 216: Update the planning_scene_monitor description to say it controls
which scene information is published, and remove the claim that it controls
publication frequency; do not name a frequency parameter unless its correct
configuration option is established.
- Line 211: Update the MoveItConfigsBuilder description to explain that, without
an explicit file path, it checks for config/robot_name.urdf.xacro and may use
the URDF location recorded in .setup_assistant before falling back to
robot_package/config/robot_name.urdf. Describe the discovery order so readers
can identify the file actually loaded.
