A web application's main purpose is to present and gather data. For this reason Angular strives to make both of these operations trivial. This example shows off how you can build a simple form to allow a user to enter data.

### Demo

## Things to notice

- The user data model is initialized `controller` and is available in the `scope` with the initial data.
- For debugging purposes we have included a debug view of the model to better understand what is going on.
- The `input directives` simply refer to the model and are data-bound.
- The inputs validate. (Try leaving them blank or entering non digits in the zip field)
- In your application you can simply read from or write to the model and the form will be updated.
- By clicking the 'add' link you are adding new items into the `user.contacts` array which are then reflected in the view.
