 Once the repository is cloned, the installation can be performed in two ways,
 depending on the choice of the user:
+
 * Run the command `python setup.py install` or `python setup.py install --user` inside the project directory. 
 * Install the module via `pip` running the command `python -m pip install` inside the project directory. It is possible to include the `--user` option and the `-e` option for editing.
