Before installing you should make sure you have a working copy of Git installed and the latest revision of repository cloned. You should also have python installed with virtualenv.
(1) Run the 'virtualenv' command to create a virtual environment in the 'env' sub-folder:
virtualenv env
(2) Install the required packages from 'requirements.txt' using 'pip' from the virtual environment:
env\Scripts\pip install -r requirements.txt
(3) Run scripts using the python executable from the installed virtual environment:
env\Scripts\python pi_web_api_test.py
(4) Configure the variables in config/pi_system.py to suit your PI system installation.
