It was designed to be user-friendly and extensive, with the hope that an average network engineer will find it easy to use. I would invite you to help with the development of it and make it even better.
You shouldered the documentation in the repository, but basically you can start with issuing
pip install mistifi
or
pip3 install mistifi
in the terminal of choice and give it a shot.
Please visit the project on GitHub and contribute. No contribution is too small, and even just documenting a few things will help, not to mention bringing you into the coding world.
