Hello world example

The hello world example in the programming phoenix book generates lots of boiler plate and gives you much more than you would get in a traditional hello world app. ie db integration, xss protection and much more. Can we find something more minimal? Can we use the phoenix framework without using auto generated boiler plate, so we can give a user an example of a hello word app with a minimal code base..

I am not sure if in this case, we would want to drop down and just use plug. This might be an option, since phoenix is built on plug..
