 Backfire is an officially supported [Backbone](http://backbonejs.org) binding for
 [Firebase](http://www.firebase.com/?utm_medium=web&utm_source=backfire).

+The bindings let you use special model and collection types that will
 automatically synchronize with Firebase, and also allow you to use regular
+`Backbone.Sync` based synchronization methods.
 
 Live Demo: <a target="_blank" href="http://firebase.github.io/backfire/examples/todos/">Real-time TODO app</a>.
 
-Usage
------
+Getting Started
+---------------
 Include both firebase.js and backbone-firebase.js in your application.
+They're both served off of Firebase's CDN, which you are welcome to use!
 
-```html
+``` html
 <script src="https://cdn.firebase.com/v0/firebase.js"></script>
-<script src="backbone-firebase.js"></script>
+<script src="https://cdn.firebase.com/libs/backfire/0.3.0/backbone-firebase.min.js"></script>
 ```
 
-There are two primary ways to use the bindings:
+You will now have access to the `Backbone.Firebase`,
+`Backbone.Firebase.Collection`, and `Backbone.Firebase.Model` objects.
 
-### METHOD 1: Backbone.Firebase.Collection
+Backbone.Firebase
+-----------------
+The bindings also override `Backbone.sync` to use Firebase. You may consider
+this option if you want to maintain an explicit seperation between _local_ and
+_remote_ data, and want to use regular Backbone models and collections.
+
+This adapter works very similarly to the
+[localStorage adapter](http://documentcloud.github.com/backbone/docs/backbone-localstorage.html)
+used in the canonical Todos example.
+
+Please see [todos-sync.js](https://github.com/firebase/backfire/blob/gh-pages/examples/todos/todos-sync.js)
+for an example of how to use this feature.
+
+### firebase
+You simply provide a `firebase` property in your collection, and that set of
+objects will be persisted at that location.
+
+``` js
+var TodoList = Backbone.Collection.extend({
+  model: Todo,
+  firebase: new Backbone.Firebase("https://<your-namespace>.firebaseio.com")
+});
+```
 
-You will have access to a new object, `Backbone.Firebase.Collection`. You
-may extend this object, and must provide a Firebase URL or a Firebase reference
-as the `firebase` property. For example:
+You can also do this with a model.
+
+``` js
+var MyTodo = Backbone.Model.extend({
+  firebase: new Backbone.Firebase("https://<your-namespace>.firebaseio.com/myTodo")
+});
+```
+
+### fetch()
+In a collection with the `firebase` property defined, calling `fetch` will
+retrieve data from Firebase update the collection with its contents.
+
+``` js
+TodoList.fetch();
+```
+
+### sync()
+In a collection with the `firebase` property defined, calling `sync` will
+set the contents of the local collection to the specifeid Firebase location.
+
+``` js
+TodoList.sync();
+```
+
+### save()
+In a model with the `firebase` property defined, calling `save` will set the
+contents of the model to the specified Firebase location.
+
+``` js
+MyTodo.save();
+```
+
+### destroy()
+In a model with the `firebase` property defined, calling `destroy` will remove
+the contents at the specified Firebase location.
+
+``` js
+MyTodo.destroy();
+```
+
+Backbone.Firebase.Collection
+----------------------------
+This is a special collection object that will automatically synchronize its
+contents with Firebase. You may extend this object, and must provide a Firebase
+URL or a Firebase reference as the `firebase` property.
+
+Each model in the collection will be treated as a `Backbone.Firebase.Model`
+(see below).
+
+Please see [todos.js](https://github.com/firebase/backfire/blob/gh-pages/examples/todos/todos.js)
+for an example of how to use this special collection object.

 var TodoList = Backbone.Firebase.Collection.extend({

 Any models added to the collection will be synchronized to the provided
 Firebase. Any other clients using the Backbone binding will also receive
 `add`, `remove` and `changed` events on the collection as appropriate.
 
-**BE AWARE!** The important difference between using a regular collection and
-a Firebase collection is that you do not need to call any functions that will
-affect _remote_ data. If you call `fetch` or `sync` on the collection, **the
-library will ignore it silently**.

+### add(model)
+Add a new model to the collection. This model will be synchronized to Firebase,

+Backbone.Firebase.Model
+-----------------------
+This is a special model object that will automatically synchronize its
+contents with Firebase. You may extend this object, and must provide a Firebase
+URL or a Firebase reference as the `firebase` property.
 
 ```js
-var TodoList = Backbone.Collection.extend({
-  model: Todo,
-  firebase: new Backbone.Firebase("https://<your-namespace>.firebaseio.com")
+var MyTodo = Backbone.Firebase.Model.extend({
+  firebase: "https://<your-firebase>.firebaseio.com/mytodo"
 });
 ```
 
-will ensure that any calls to `fetch` or `sync` on the collection will update
-the provided Firebase with the appropriate data. The same is true for the
-`save` and `destroy` methods on a model.
+You may apply limits as with `Backbone.Firebase.Collection`.

--------
-[MIT](http://firebase.mit-license.org).
+You should modify your model as you normally would, (via `set` and `destroy`)
+and _remote_ data will be instantly updated.
+
+### set(value)
+Sets the contents of the model and updates it in Firebase.
+
+``` js
+MyTodo.set({foo: "bar"}); // Model is instantly updated in Firebase (and other clients).
+```
+
+### destroy()
+Removes the model locally, and from Firebase.
+
+``` js
+MyTodo.destroy(); // Model is instantly removed from Firebase (and other clients).
