+            No worries friend! We have you covered!
+            If you have a blank list when you first start the program, that's normal! You just have to search for somebody.
+            Click on the Search button and type away in the name field! If you get an error in response to your search query, that means that user doesn't exist.
+            If the search finds a user, the list will populate. Click on a repository of interest and click on the Detail button to view it in action.
+            You found a problem with the program? Great! Click on the Feedback button to send an email to me and I will respond to said email as soon as possible.
