To use Ember 2.0 with Ember CLI 1.13.x, you just need to upgrade the Ember dependency.

    bower install --save ember#2.0.0
    bower install --save ember-data#2.0.0-beta.1

If you have trouble, feel free to pop into the Ember Community Slack or use another resource for Q/A. Links are at: http://emberjs.com/community/

TL;DR We will be following with a new CLI shortly shortly
