+- Set up *Script Path* and *Working Directory* as follows:
 
 Paths for running a Debug build:
---------------------------------

 Common errors
 -------------
 
     qtpy.PythonQtError: No Qt bindings could be found
 
-``<Mantid Source Directory>/external/src/ThirdParty/lib/qt5/bin`` is missing from ``Path``
+``<Mantid Source Directory>/external/src/ThirdParty/lib/qt5/bin`` is missing from the ``Path`` environment variable.
 
     ImportError: DLL load failed: The specified module could not be found.
 
-``<Mantid Source Directory>/external/src/ThirdParty/lib/qt5/lib`` is missing from ``Path``
+``<Mantid Source Directory>/external/src/ThirdParty/lib/qt5/lib`` is missing from the ``Path`` environment variable.
 
-The fix for these errors is to make sure you have started PyCharm through the ``<Mantid Build Directory>/pycharm.bat`` script. This sets up the ``PATH`` variable for the Python imports.

-Additionally, check that your PyCharm Run/Debug configuration *does not* overwrite the ``PATH`` variable. To check go to ``Edit Configurations -> Environment Variables`` and click the folder icon on the right side. In the ``Name`` column there should not be a ``Path`` variable.

 Identifying issues with PyCharm configuration
 ---------------------------------------------
 Follow these steps to narrow down the root of potential errors:
+
 - Go to the Mantid Build Directory
-- Start ``command_prompt.bat``. If the ``command_prompt.bat`` file is missing, Mantid has not been built.
+- Start ``command_prompt.bat``. If the ``command_prompt.bat`` file is missing, the build has not been fully generated from `CMake` or is corrupted.
 - In the command prompt open the Python interpreter with ``python``.
-- Try to import the package where the error is happening
+- Try to import the package where the error is happening. For example if there is an error on ``import qtpy``, ``from PyQt5 import QtCore``, try running that line in the interpreter.
 - If the import succeeds, then there is a problem with the ``PATH`` configuration in PyCharm.
 - If the import fails, then it is possible that Mantid has not been fully built. If you are trying to import ``PyQt4``/``PyQt5``/``qtpy``, and it fails to import from the command prompt, then the ``external`` dependencies might not be dowloaded or are corrupted.
