+Material Design Icons
+=====================
+
+A set of icons designed under the
+[material design guidelines](http://www.google.com/design/spec).
+
+License
+-------
+
+We have made these icons available for you to incorporate them into your
+products under the Creative Common Attribution 4.0 International License
+(CC-BY 4.0). Feel free to remix and re-share these icons and documentation in
+your products. We'd love attribution in your app's about screen, but it's not
+required. The only thing we ask is that you not re-sell the icons themselves.
