How to use Ember.Object create model?

I want to use Ember Object for my apps’ model.

I create a application use Ember Data, but I don’t know how to use it, and met a lot of problems.

Ember data’s document is introduced too little.

But I search in the google just find this: embersherpa.com

I read the discourse code, and it use App.Model.extend to set a model. Do you have more about how to Use Ember setting the model?

Thanks.
