 > Provider-hosted add-ins written in JavaScript must use the SP.RequestExecutor cross-___domain library to send requests to a SharePoint ___domain. For an example, see [upload a file by using the cross-___domain library](https://msdn.microsoft.com/en-us/library/office/dn450841.aspx).

 To use the examples in this article, you'll need the following:
 
 - SharePoint Server or SharePoint Online.
-
 - **Write** permissions to the **Documents** library for the user running the code. If you're developing a SharePoint Add-in, you can specify **Write** add-in permissions at the **List** scope.
-
 - Browser support for the **FileReader** API (HTML5).
-
 - A reference to the jQuery library in your page markup. For example:

+
     ```HTML
     <script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.9.1.min.js" type="text/javascript"></script>
     ```

     ```HTML
     <input id="getFile" type="file"/><br />
     <input id="displayName" type="text" value="Enter a unique name" /><br />
