+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" secondaryProgesss="30"></paper-progress>
+
+Styling progress bar:
+
+To change the active progress bar color:
+
+    paper-progress::shadow #activeProgress {
+      background-color: #e91e63;
+    }
+
+To change the secondary progress bar color:
+
+    paper-progress::shadow #secondaryProgress {
+      background-color: #f8bbd0;
+    }
+    
+To change the progress bar background color:
+
+    paper-progress::shadow #progressContainer {
+      background-color: #64ffda;
+    }
