download an appropriate version of Python: https://www.python.org/ (for windows users, I recommand the portable version of Python: http://winpython.github.io/ - I personnaly use WinPython 3.6.1.0Qt5-64bit)
download the whole repo and put it wherever you please
use Spyder.exe (it is a code editor that allows you to run your program using F5) to open and run stochastic_breakout.py
errors should then appear, stating the various modules that you miss
install the modules that you miss using Python Command Prompt with: "pip install module_name"
here are the modules that you should miss: pygame, configparser
