First, you need to have a working Erlang environment.
make run
The app listens by default on the port 8080 or the one defined in the PORT
environment variable.
Create an application on https://scalingo.com, then:
git remote add scalingo git@scalingo.com:<name_of_your_app>.git
git push scalingo master
And that's it!
The application is running at this url: https://sample-erlang.osc-fr1.scalingo.io/
