-Pyreverse Configuration
-^^^^^^^^^^^^^^^^^^^^^^^
 
+``pyreverse`` is run from the command line using the following syntax::
+
+  pyreverse [options] <packages>
+
+where ``<packages>`` is one or more Python packages or modules to analyze.
+
+The available options are organized into the following categories:
+
+* :ref:`filtering-and-scope` - Control which classes and relationships appear in your diagrams
+* :ref:`display-options` - Customize the visual appearance including colors and labels
+* :ref:`output-control` - Select output formats and set the destination directory
+* :ref:`project-configuration` - Define project settings like source roots and ignored files

 Pyreverse
----------
+=========
 
-``pyreverse`` analyzes your source code and generates package and class diagrams.
+``pyreverse`` is a powerful tool that creates UML diagrams from your Python code. It helps you visualize:
 
-It supports output to ``.dot``/``.gv``, ``.puml``/``.plantuml`` (PlantUML) and ``.mmd``/``.html`` (MermaidJS) file formats.
-If Graphviz (or the ``dot`` command) is installed, all `output formats supported by Graphviz <https://graphviz.org/docs/outputs/>`_
-can be used as well. In this case, ``pyreverse`` first generates a temporary ``.gv`` file, which is then
-fed to Graphviz to generate the final image.
+- Package dependencies and structure
+- Class hierarchies and relationships
+- Method and attribute organization
 
-Running Pyreverse

+Output Formats
+==============
 
-To run ``pyreverse``, use::
+``pyreverse`` supports multiple output formats:
 
-  pyreverse [options] <packages>
+* Native formats:
+    * ``.dot``/``.gv`` (Graphviz)
+    * ``.puml``/``.plantuml`` (PlantUML)
+    * ``.mmd``/``.html`` (MermaidJS)
 
-<packages> can also be a single Python module.

-For example, running::
