How to add API keys and other protected things to the hero?

Question

I read somewhere, but can't find where to add secret keys to Heroku without putting them in the git repository source code?

I think this helps protect it when I click on github.

How do I do this and what makes sense?

http://docs.heroku.com/config-vars

Then add development keys to the initializer:

#config/initializers/keys.rb development: SOME_KEY = 'abc123' #not your production key testing: SOME_KEY = 'abc123' #not your production key #production: #blank 

Optionally add an initializer to .gitignore. Not required as your production key is not saved.
