HELP ME SETUP A GITHUB PROJECT

Hello, I am completely new to python and scripting and im having trouble setting up a script. This script is used so that it automatically bets on this roullete and if i lose it doubles the bet and it continues to double until i win and it goes back to the initial amount. if anyone can help me set this up that would be appreciated. can you give me a step by step tutorial or maybe i can screenshare, i really need this. https://github.com/carince/bloxflip-autogambler .when i setup i paste "copy(localStorage.getItem(_DO_NOT_SHARE_BLOXFLIP_TOKEN))" into the dev console it says "undefined". also when i type "npm i" or "npm start" it gives me a bunch of errors.
