+<!--
+`<paper-input-container>` is a container for a `<label>`, an `<input is="iron-input">` or
+`<iron-autogrow-textarea>` and optional add-on elements such as an error message or character
+counter, used to implement Material Design text fields.
+
+For example:
+
+    <paper-input-container>
+      <label>Your name</label>
+      <input is="iron-input">
+    </paper-input-container>
+
+### Listening for input changes
+
+By default, it listens for changes on the `bind-value` attribute on its children nodes and perform
+tasks such as auto-validating and label styling when the `bind-value` changes. You can configure
+the attribute it listens to with the `attr-for-value` attribute.
+
+### Using a custom input element
+
+You can use a custom input element in a `<paper-input-container>`, for example to implement a
+compound input field like a social security number input. The custom input element should have the
+`paper-input-input` class, have a `notify:true` value property and optionally implements
+`Polymer.IronValidatableBehavior` if it is validatble.
+
+    <paper-input-container attr-for-value="ssn-value">
+      <label>Social security number</label>
+      <ssn-input class="paper-input-input"></ssn-input>
+    </paper-input-container>
+
+### Validation
+
+If the `auto-validate` attribute is set, the input container will validate the input and update
+the container styling when the input value changes.
+
+### Add-ons
+
+Add-ons are child elements of a `<paper-input-container>` with the `add-on` attribute and
+implements the `Polymer.PaperInputAddonBehavior` behavior. They are notified when the input value
+or validity changes, and may implement functionality such as error messages or character counters.
+They appear at the bottom of the input.
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-input-container-color` | Label and underline color when the input is not focused | `--secondary-text-color`
+`--paper-input-container-focus-color` | Label and underline color when the input is focused | `--default-primary-color`
+`--paper-input-container-invalid-color` | Label and underline color when the input is focused | `--google-red-500`
+`--paper-input-container-input-color` | Input foreground color | `--primary-text-color`
+`--paper-input-container` | Mixin applied to the container | `{}`
+`--paper-input-container-label` | Mixin applied to the label | `{}`
+`--paper-input-container-input` | Mixin applied to the input | `{}`
+
+This element is `display:block` by default, but you can set the `inline` attribute to make it
+`display:inline-block`.
