+Element providing material design circular spinner.
+
+    <paper-spinner active></paper-spinner>
+
+The default spinner cycles between four layers of colors; by default they are
+blue, red, yellow and green. It can be customized so that it uses one color only
+by setting all the layer colors to the same value.
+
+### Accessibility
+
+Alt attribute should be set to provide adequate context for accessibility. If not provided,
+it defaults to 'loading'.
+Empty alt can be provided to mark the element as decorative if alternative content is provided
+in another form (e.g. a text block following the spinner).
+
+    <paper-spinner alt="Loading contacts list" active></paper-spinner>
+
+### Styling
+
+The following custom properties and mixins are available for styling:
+
+Custom property | Description | Default
+----------------|-------------|----------
+`--paper-spinner-layer-1-color` | Color of the first spinner rotation | `--google-blue-500`
+`--paper-spinner-layer-2-color` | Color of the second spinner rotation | `--google-red-500`
+`--paper-spinner-layer-3-color` | Color of the third spinner rotation | `--google-yellow-500`
+`--paper-spinner-layer-4-color` | Color of the fourth spinner rotation | `--google-green-500`
