From a terminal run the following commands:
git clone email@example.com:emberjs/ember.js cd ember.js npm install npm start
While that is running open another terminal and run the following (starting from the
ember.js folder you cloned a moment ago):
cd dist bower link
Now navigate to your Ember CLI application, and run:
bower link ember
Now the changes you make to the ember.js repo, should be reflected live in your running Ember CLI project.
