 ## Summary
 Sample Search Web Part that illustrates how you can use Angular within the new SharePoint Framework
 
+![Sample of the search web part](./assets/angularSearch.png)
 This app uses SharePoint's Search REST API endpoint to query listitems of a specific content type and displays the results to the end user.
 Ideally instead of selecting a content type for the search you would want to select a Result Source, but currently Result Sources are not
 through SharePoint's REST API.
