+`<iron-input>` adds two-way binding and custom validators using `Polymer.IronValidatorBehavior`
+to `<input>`.
+
+### Two-way binding
+
+By default you can only get notified of changes to an `input`'s `value` due to user input:
+
+    <input value="{{myValue::input}}">
+
+`iron-input` adds the `bind-value` property that mirrors the `value` property, and can be used
+for two-way data binding. `bind-value` will notify if it is changed either by user input or by script.
+
+    <input is="iron-input" bind-value="{{myValue}}">
+
+### Custom validators
+
+You can use custom validators that implement `Polymer.IronValidatorBehavior` with `<iron-input>`.
+
+    <input is="iron-input" validator="my-custom-validator">
+
+### Stopping invalid input
+
+It may be desirable to only allow users to enter certain characters. You can use the
+`prevent-invalid-input` and `allowed-pattern` attributes together to accomplish this. This feature
+is separate from validation, and `allowed-pattern` does not affect how the input is validated.
+
+    <!-- only allow characters that match [0-9] -->
+    <input is="iron-input" prevent-invaild-input allowed-pattern="[0-9]">
