@ -65,7 +65,11 @@ var WithLink = React.createClass({
`ReactLink` objects can be passed up and down the tree as props, so it's easy (and explicit) to set up two-way binding between a component deep in the hierarchy and state that lives higher in the hierarchy.
Note that `<input>` supports ReactLink for both `value` and `checked`.
Note that checkboxes have a special behavior regarding their `value` attribute, which is the value that will be sent on form submit if the checkbox is checked (defaults to `on`). The `value` attribute is not updated when the checkbox is checked or unchecked. For checkboxes, you should use `checkedLink` instead of `valueLink`:
```
<input type="checkbox" checkedLink={this.linkState('booleanValue')} />
```
