Developing on Ember master (linked locally), with an Ember CLI application.

ember-master-in-ember-cli-app.md

From a terminal run the following commands:

git clone git@github.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.
