$ cd python-getting-started

$ python3 -m venv getting-started
$ pip install -r requirements.txt

$ createdb python_getting_started

$ python manage.py migrate
$ python manage.py collectstatic

$ heroku local - for linux
$ heroku local web -f Procfile.windows - for win

Your app should now be running on localhost:5000.

Deploying to Heroku

$ heroku create
$ git push heroku master

$ heroku run python manage.py migrate
