  Lastly, for installation, return to the root directory of the hdlConverter repo. This should be accessible via:
  -.. code:: batch
  +.. code-block::

  cd ../../../../
  Once you return to the root directory, run:
  -.. code:: batch

  %PYTHON%\\python.exe -m pip install jupyter git+https://github.com/Nic30/hdlConvertorAst.git
  %PYTHON%\\python.exe -m pip install -r requirements.txt
  Finally, to build and install the library:
  -.. code:: batch
  +.. code-block::
  +
  %PYTHON%\\python.exe setup.py install -- -DJava_JAR_PATHS="C:\\The_Directory_Containing_The_JAR_File" -DANTLR4CPP_ROOT="C:\\Program Files\\LIBANTLR4" -G"Visual Studio 16 2019" -A x64
  Note that if you run the python in hdlConvertor root directory just after installation the python will import the hdlConvertor directory instead
  installed and module. Thus you will recieve some import errors about missing library which is build from c++.
  In order to prevent that you can delete or rename hdlConvertor direcotory or you can run python in a different folder.
  -.. code:: batch
  +.. code-block::

  rmdir /s /q hdlConvertor
