+Extension template
+==================
+
+Template to help the user create an extension from scratch.
+
+The extension provides a graphical user interface for configuration, or it can be used in batch mode via command line arguments.
+
+The following image shows the extension user interface:
+
+.. image:: ../../../_static/extensions/extension_template.png
+  :width: 800
+  :alt: Extension template UI
+
+
+Features
+--------
+
+- Create a sphere providing information such as the origin coordinates and radius.
+- Allow users to browse and select an **.aedt** file to load in AEDT.
+- Display name of the active project.
+- Support of light and dark themes for the GUI.
+
+Run the extension
+-----------------
+
+The extension can be run from a Python script in the following way:
+
+.. code:: python
+
+    import ansys.aedt.core
+    import os
+
+    from ansys.aedt.core.workflows.templates.template_get_started import main
+
+    hfss = ansys.aedt.core.Hfss()
+
+    # Specify the AEDT session to connect
+    os.environ["PYAEDT_SCRIPT_PORT"] = str(hfss.desktop_class.port)
+    os.environ["PYAEDT_SCRIPT_VERSION"] = hfss.desktop_class.aedt_version_id
+
+    main({"origin_x": 2, "radius": 6, "is_test": True})
+
+Command line
+------------
+
+The extension can also be run directly via the command line for batch processing.
+
+The script accepts the following arguments:
+- ``**origin_x**`` : x origin coordinate.
+- ``**origin_y**`` : y origin coordinate.
+- ``**origin_z**`` : z origin coordinate.
+- ``**radius**`` : radius.
+- ``**file_path**`` : file path to the **.aedt** file.
+
+Use the following syntax to run the extension:
+
+.. toctree::
+   :maxdepth: 2

+   ../commandline
