+`paper-radio-group` allows user to select only one radio button from a set.
+Checking one radio button that belongs to a radio group unchecks any
+previously checked radio button within the same group. Use
+`selected` to get or set the selected radio button.
+
+Example:
+
+    <paper-radio-group selected="small">
+      <paper-radio-button name="small" label="Small"></paper-radio-button>
+      <paper-radio-button name="medium" label="Medium"></paper-radio-button>
+      <paper-radio-button name="large" label="Large"></paper-radio-button>
+    </paper-radio-group>
+
+See <a href="paper-radio-button.html">paper-radio-button</a> for more
+information about `paper-radio-button`.
