 # iron-input
-An input with data binding
+
+An input with data binding.
+
+By default you can only get notified of changes to an `input`'s `value` due to user input:
+
+```html
+<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.
+
+```html
+<input is="iron-input" bind-value="{{myValue}}">
+```
