If you want to run this app locally on your machine make sure to create a file called .env with these contents:
APIKEY=YOUR_API_KEY_HERE
and start it by using foreman start.
If you want to start it without the Heroku Toolbelt you have to put this env variable somewhere in your current session.
You can put it in any of your .profile's or EXPORT it simply. This is up to you!
