In order to get started you will need python3 and nodejs installed. If you dont know how to do that I would suggest that you shouldnt be using this.
Fingers crossed all the node modules you should need are already there if not you will need to do npm i dotenv. You will also need to make a .env file with the parts from .env.example filled in.
Once thats all done just run node index.js and your timetable will be ready in json form!
