+Material design: [Progress & activity](https://www.google.com/design/spec/components/progress-activity.html)
+
+The progress bars are for situations where the percentage completed can be
+determined. They give users a quick sense of how much longer an operation
+will take.
+
+Example:
+
+    <paper-progress value="10"></paper-progress>
+
+There is also a secondary progress which is useful for displaying intermediate
+progress, such as the buffer level during a streaming playback progress bar.
+
+Example:
+
+    <paper-progress value="10" secondary-progress="30"></paper-progress>
+
+### Styling progress bar:
+
+To change the active progress bar color:
+
+    paper-progress {
+       --paper-progress-active-color: #e91e63;
+    }
+
+To change the secondary progress bar color:
+
+    paper-progress {
+      --paper-progress-secondary-color: #f8bbd0;
+    }
+
+To change the progress bar background color:
+
+    paper-progress {
+      --paper-progress-container-color: #64ffda;
+    }
+
+Add the class `transiting` to a paper-progress to animate the progress bar when
+the value changed. You can also customize the transition:
+
+    paper-progress {
+      --paper-progress-transition-duration: 0.08s;
+      --paper-progress-transition-timing-function: ease;
+      --paper-progress-transition-transition-delay: 0s;
+    }
+
+The following mixins are available for styling:
+
+Custom property                               | Description                                 | Default
+----------------------------------------------|---------------------------------------------|--------------
+`--paper-progress-container-color`            | Mixin applied to container                  | `--google-grey-300`
+`--paper-progress-transition-duration`        | Duration of the transition                  | `0.008s`
+`--paper-progress-transition-timing-function` | The timing function for the transition      | `ease`
+`--paper-progress-transition-delay`           | delay for the transition                    | `0s`
+`--paper-progress-active-color`               | The color of the active bar                 | `--google-green-500`
+`--paper-progress-secondary-color`            | The color of the secondary bar              | `--google-green-100`
+`--paper-progress-disabled-active-color`      | The color of the active bar if disabled     | `--google-grey-500`
+`--paper-progress-disabled-secondary-color`   | The color of the secondary bar if disabled  | `--google-grey-300`
+`--paper-progress-height`                     | The height of the progress bar              | `4px`
