+Blender Addon + VS Code Debugger
+------------------------------
+
+Setting up debugging with Blender Addon is a bit simpler as it doesn't require Blender to be started in a special way
+and debugger can be always attached later when it's needed.
+
+1. Install Hextant Python Debugger Blender addon from `official repository <https://github.com/hextantstudios/hextant_python_debugger#installation>`_.
+
+2. Open IfcOpenShell repository in VS Code and setup configuration for attaching debugger `per the instructions <https://github.com/hextantstudios/hextant_python_debugger#debug-a-blender-add-on-from-visual-studio-code>`_.
+
+3. Start Debug Server in Blender (Blender -> System -> Start Debug Server)
+
+4. VS Code -> Run and Debug -> "Python Debugger: Remote Attach" in dropdown -> Start Debugging
+
+5. Now debugger is attached to Blender. You can set breakpoints in VS Code and use Debug Console.
