 While CLion supports both a C++ debugger and a Python debugger, it generally does not support
 embedded Python interpreters, nor debugging both simultaneously.  However, there are workaround
 procedures that will allow this.

 ### Setting up for python debugging in CLion
 
-Install pydevd in the interpreter that FreeCAD is using.  'pip3 install pydevd' from the correct
-venv is one way to accomplish this.

 Use the settings button in the upper right, the File Menu -> Settings, or the Ctrl-Alt-S shortcut
 to open the settings dialog, expand the Build, Execution, Deployment tree item, and select a Python
 Interpreter:

+Install `pydevd` into the FreeCAD python environment, if it is not already present. For example,
+```
+C:\Users\jdoe\FreeCAD\cmake-build-relwithdebinfo-visual-studio\bin\python.exe -m pip install pydevd
+```
 Switch to the Python Debugger settings, and change the Attach To Process name from python to 'Freecad'
 You may need to change this back if you use the IDE for other applications.

 Now there are three approaches here:
