	pip install psycopg2
	# And NOW… you’ll be able to install django-heroku 
	pip install gunicorn
	pip install django-heroku
	pip freeze > requirements.txt

Step 3. In your app/settings.py

	import django_heroku 

	# Then all the way at the bottom of the file
	# ... 

	django_heroku.settings(locals()) 

Step 4. push it to heroku

	# login to your heroku
	heroku login

	# create new app if one doesn't yet exist
	heroku create

	# create a new postgres database for your app
	heroku addons:create heroku-postgresql:hobby-dev

	# migrate your database to the heroku app
	heroku run python manage.py migrate

	# before you do this, make sure to add your SECRET_KEY to your env variables in your heroku app settings
	git add .
