How can I set up cloudinary.yml using environment variables?
I'm using Rails 4, github and deploying to Heroku.
It's my understanding that it's a bad idea for me to publish the API secret and key directly onto to github. I understand the solution might be to use environment variables instead. Do you have an example of how to do that? What should be in my cloudinary.yml file and what are the commands for setting environment variables on Heroku?
