 You will need a consumer key and access token to query your user data with the Pocket API. To create those credentials:
 * Follow the documentation on the [Pocket: Developer API](https://getpocket.com/developer/) site.
 * Use one of the many third-party Pocket credential creation tools like [OneClickPocket](http://reader.fxneumann.de/plugins/oneclickpocket/auth.php) or [pocket-auth](https://github.com/mheap/pocket-auth).

+## Preferences
+
+The Pocket widget can be easily modified with these three lines of code in the pocket_widget.js file:
+
+```
+let attributes = {
+	"consumerKey": "YOUR-CONSUMER-KEY",
+	"accessToken": "YOUR-ACCESS-TOKEN",
+	"favorite": 1  // Enter 0 for "Unread"; enter 1 for "Favorites"
+} 
+```
+Replace YOUR-CONSUMER-KEY and YOUR-ACCESS-TOKEN with the respective consumer key and access token for your account. To show your two most recent Pocket favorites in the widget, leave the "favorite" value as 1; changing the "favorite" value to 0 will show your two most recent unread saved articles. No modification of the pocket_widget/pocket_widget_code.js file is necessary.
