As :pep:517 does not provide a way to install for development purpose, it is necessary to follow these steps to install for development :

.. code-block:: SH

   mv pyproject.toml pyproject.toml\~
   pip3 install --user -e ".[docker,import_sql,conf2reST,source_control]" --upgrade
   mv pyproject.toml\~ pyproject.toml
