 			Click on the browse button. This will open up a window. Select the zip file of questions and click Ok and then click on Upload file button, questions will be uploaded and displayed on the Questions page.
 
+				Zip file should contain **questions_dump.json** from which questions will be loaded.
+				Zip file can contain files related to questions.
+				Sample entry in **questions_dump.json** is as shown below. ::
