+Material design: [Radio button](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-radio-button)
+
+`paper-radio-button` is a button that can be either checked or unchecked.
+User can tap the radio button to check or uncheck it.
+
+Use a `<paper-radio-group>` to group a set of radio buttons.  When radio buttons
+are inside a radio group, exactly one radio button in the group can be checked
+at any time.
+
+Example:
+
+    <paper-radio-button></paper-radio-button>
+    <paper-radio-button>Item label</paper-radio-button>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-radio-button-unchecked-background-color` | Radio button background color when the input is not checked | `transparent`
+`--paper-radio-button-unchecked-color` | Radio button color when the input is not checked | `--primary-text-color`
+`--paper-radio-button-unchecked-ink-color` | Selected/focus ripple color when the input is not checked | `--primary-text-color`
+`--paper-radio-button-checked-color` | Radio button color when the input is checked | `--primary-color`
+`--paper-radio-button-checked-ink-color` | Selected/focus ripple color when the input is checked | `--primary-color`
+`--paper-radio-button-size` | Size of the radio button | `16px`
+`--paper-radio-button-ink-size` | Size of the ripple | `48px`
+`--paper-radio-button-label-color` | Label color | `--primary-text-color`
+`--paper-radio-button-label-spacing` | Spacing between the label and the button | `10px`
+`--paper-radio-button-radio-container` | A mixin applied to the internal radio container | `{}`
+`--paper-radio-button-label` | A mixin applied to the internal label | `{}`
+`--paper-radio-button-label-checked` | A mixin applied to the internal label when the radio button is checked | `{}`
+
+This element applies the mixin `--paper-font-common-base` but does not import `paper-styles/typography.html`.
+In order to apply the `Roboto` font to this element, make sure you've imported `paper-styles/typography.html`.
