This quickstart guide should get you from zero to slightly-more-than-zero in a couple of minutes. When done, you should feel somewhat confident that ember.js actually works and hopefully will be interested enough to learn more.
WARNING: Don't just try this guide then think ember-sucks cause "I could write that quickstart-guide better in jQuery or Fortran" or whatever. I am not trying to sell you on ember or anything, this guide is little more than a hello-world.
