1. Clone this repo
2. In the repo directory, make a new virtualenv using virtualenv vendor
3. Activate it using source vendor/bin/activate
4. Install requirements to the virtualenv using pip install -r requirements.txt
5. Whenever you want to run the code, activate the virtualenv by running source vendor/bin/activate again
