I included a demo layout with sample Ember templates and controllers. Template from here.

You may also want to checkout the Ember.js with Middleman example.
Install middleman:
gem install middleman
Clone the repo:
$ git clone git@github.com:landonmarder/ember-middleman-demo.git <PROJECT NAME>
Then bundle, and start the middleman server
bundle
middleman server
You can read more about project templates on the Middleman site.
