+
+`paper-button` is a button containing text or an image. When the user touches
+the button, a ripple effect emanates from the point of contact.
+
+A `paper-button` may be flat or raised. A raised button behaves like a piece
+of paper resting on another sheet, and lifts up upon press. Flat buttons do
+not raise up. Add the `raisedButton` attribute to make a raised button.
+
+Example:
+
+    <paper-button label="flat button"></paper-button>
+    <paper-button label="raised button" raisedButton></paper-button>
+
+A button should be styled with a background color, text color, ripple color
+and hover color.
+
+To style the background, text and hover color, apply the `background` and
+`color` CSS properties to the button. To style the ripple color, apply the
+`color` CSS property to the `#ripple` element in the button's shadow root:
+
+    /* Style #my-button blue with white text and darker blue ink. */
+    #my-button {
+        background: #4285f4;
+        color: #fff;
+    }
+
+    #my-button:hover {
+        background: #2a56c6;
+    }
+
+    #my-button::shadow #ripple {
+        color: #2a56c6;
+    }
