-  Material design buttons that mimic GAIA's buttons.
+  Material design buttons for OOBE screens.
+
+  Attributes:
+    'disabled' - button is disabled when the attribute is set.
 
   Example:
-    <gaia-button type="dialog"></gaia-button>
-
-  Attributes:
-    'type' - there are three kinds of button: regular blue button (none type
-             provided), dialog button (type="dialog") and a button that looks
-             more like a link (type="link").
-    'disabled' - button is disabled when the attribute is set.
+    <oobe-button type="dialog"></oobe-button>

Linked stylesheets are deprecated. Maybe inline the css?

Linked stylesheets are OK in Chrome code, because they are inlined by GRIT
during compilation. I prefer to leave CSS in a separate files. Otherwise CSS
style checks are not launched.

-      <paper-button id="button" disabled="[[disabled]]"
