+Material design: [Buttons](https://www.google.com/design/spec/components/buttons.html)
+
+`paper-button` is a button. When the user touches the button, a ripple effect emanates
+from the point of contact. It may be flat or raised. A raised button is styled with a
+shadow.
+
+Example:
+
+    <paper-button>Flat button</paper-button>
+    <paper-button raised>Raised button</paper-button>
+    <paper-button noink>No ripple effect</paper-button>
+    <paper-button toggles>Toggle-able button</paper-button>
+
+A button that has `toggles` true will remain `active` after being clicked (and
+will have an `active` attribute set). For more information, see the `Polymer.IronButtonState`
+behavior.
+
+You may use custom DOM in the button body to create a variety of buttons. For example, to
+create a button with an icon and some text:
+
+    <paper-button>
+      <iron-icon icon="favorite"></iron-icon>
+      custom button content
+    </paper-button>
+
+### Styling
+
+Style the button with CSS as you would a normal DOM element.
+
+    paper-button.fancy {
+      background: green;
+      color: yellow;
+    }
+
+    paper-button.fancy:hover {
+      background: lime;
+    }
+
+    paper-button[disabled],
+    paper-button[toggles][active] {
+      background: red;
+    }
+
+By default, the ripple is the same color as the foreground at 25% opacity. You may
+customize the color using the `--paper-button-ink-color` custom property.
+
+The following custom properties and mixins are also available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-button-ink-color` | Background color of the ripple | `Based on the button's color`
+`--paper-button` | Mixin applied to the button | `{}`
+`--paper-button-disabled` | Mixin applied to the disabled button. Note that you can also use the `paper-button[disabled]` selector | `{}`
+`--paper-button-flat-keyboard-focus` | Mixin applied to a flat button after it's been focused using the keyboard | `{}`
+`--paper-button-raised-keyboard-focus` | Mixin applied to a raised button after it's been focused using the keyboard | `{}`
