How to retrieve data using an Ember Local Storage Adapter?

I'm trying to understand how the Ember Local Storage addon works. It looks like when you use the local storage adapter, there is no way to make a request to the server anymore (tell me if I'm wrong).

So I was wondering if there is a way to retrieve my models from the server, and keep them saved in the local storage?

What is the best practise to do that?

Thanks.
