 **Behavior Trees** and **State Machines**, which can be used together to create complex AI behaviors.

+Creating Behavior Trees
+=======================
+
+This chapter describes how to create and debug behavior trees.
+
+Add a Behavior Tree to an agent
+-------------------------------
+
+Follow these steps to add a behavior tree to a new or existing agent:
+
+1. Make a scene file for your agent, or open an existing scene.
+2. Add a :ref:`BTPlayer<class_BTPlayer>` node to your scene.
+3. Select :ref:`BTPlayer<class_BTPlayer>`, and create a new behavior tree in the inspector.
+4. Optionally, you can save the behavior tree to a file using the property's context menu.
+5. Click the behavior tree property to open it in the LimboAI editor.
+
+Debugging Behavior Trees
+------------------------
+
+In Godot Engine, follow to "Bottom Panel > Debugger > LimboAI" tab. With the LimboAI debugger,
+you can inspect any currently active behavior tree within the running project. The debugger can be detached
+from the main editor window, which can be particularly useful if you have a HiDPI or a secondary display.

+We target the latest stable version of the Godot Engine for development until a

+If you want to contribute to the project, please ensure that you are using the
+corresponding Godot version.
+
+We follow the `Godot code style guidelines <https://docs.godotengine.org/en/stable/contributing/development/code_style_guidelines.html#doc-code-style-guidelines>`_.
+Please use ``clang-format`` to maintain consistent styling. You can install
+``pre-commit`` hooks for Git using ``pre-commit install`` to automate this process.
+
+Please keep the minor versions backward-compatible when submitting pull requests.
+
+We support building LimboAI as a module for the Godot Engine and as a GDExtension library.
+Make sure your contribution is compatible with both. Our CI workflow will verify
+that your changes can be compiled in both configurations.
+
+Compiling as module of the Godot Engine
+---------------------------------------
+
+1. Clone the Godot Engine repository.
+2. Switch to the latest stable tag.
+3. Clone the LimboAI repository into the ``modules/limboai`` directory.
+
+.. code-block:: bash
+
+   git clone https://github.com/godotengine/godot.git
+   git checkout 4.3-stable  # Replace "4.3-stable" with the latest stable tag

+
+Consult the `Godot Engine documentation <https://docs.godotengine.org/en/stable/contributing/development/compiling/index.html>`_
+for detailed instructions on building the engine.
+
+**Unit tests** can be compiled using the ``tests=yes`` build option. To execute them,
+run the compiled Godot binary with the ``--test --tc="*[LimboAI]*"`` command-line options.
+
+Compiling as GDExtension library
+--------------------------------
+
+You'll need the SCons build tool and a C++ compiler. See also `Compiling <https://docs.godotengine.org/en/stable/contributing/development/compiling/index.html>`_.
+Run ``scons target=editor`` to build the plugin library for your current platform.
+
+- SCons will automatically clone the ``godot-cpp`` repository if it doesn't already exist in the ``limboai/godot-cpp`` directory.
+- By default, built targets are placed in the demo project: ``demo/addons/limboai/bin/``.
+
+Check ``scons -h`` for other options and targets.
+
+Contributing to the documentation
+---------------------------------
+
+Online documentation is created using `Sphinx <https://www.sphinx-doc.org/en/master/>`_.
+Source files are located in the ``doc/source`` directory in RST format and can
+be built locally with ``sphinx-build``. See the
+`Sphinx documentation <https://www.sphinx-doc.org/en/master/tutorial/getting-started.html>`_
+for more details.
+
+Class documentation resides in XML files within the ``doc_classes/`` directory.
+If you create a new class or modify an existing one, you can run the compiled
+Godot binary with the ``--doctool`` option in the root of the Godot source code
+to generate the missing XML files or sections within those files in the class documentation.
+After editing the XML files, please run the compiled editor binary with the ``--doctool``
+option again to update and tidy up the XML files.
+
+Sphinx RST files for the class documentation are generated from
+XML files using the Godot script ``make_rst.py`` and stored in the ``doc/source/classes`` directory.
+This process is performed using our own script ``gdextension/update_rst.sh``. RST files

-Debugging behavior trees
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-In Godot Engine, follow to "Bottom Panel > Debugger > LimboAI" tab. With the LimboAI debugger,
-you can inspect any currently active behavior tree within the running project. The debugger can be detached
-from the main editor window, which can be particularly useful if you have a HiDPI or a secondary display.
