+#Webtorrent User Story 1 -- Resume/Pause:
+As a user, I want to be able to pause my torrent while seeding or downloading and be able to resume progress after pausing my torrent.
+
+#Webtorrent User Story 2 -- Search:
+As a user, I want to be able to find and download a torrent by searching torrents online.
+
+####Scenario S1.1: After I have created a new Torrent, and it has started downloading,
+When I call the pause() function
+Then my torrent will pause
+And then my torrent will stop downloading
+
+####Scenario S1.2: After I have created a new Torrent,
+And I have paused my torrent
+When I call the resume() function
+Then my torrent will resume downloading
+And my torrent will pick up progress from last pause
+
+####Scenario S1.3: After I have created a new Torrent,
+And it has started downloading,
+When I call the resume() function,
+Then my RESUME will not execute
+
+####Scenario S1.4: After I have created a new Torrent,
+And it has been paused
+When I call the pause() function,
+Then my PAUSE will not execute,
+And my Torrent will still be paused
+
+####Scenario S1.5: After I have created a new Torrent,
+And I have started downloading it ,
+And my torrent has finished downloading
+When I call the pause() function,
+Then my PAUSE will not execute
+
+####Scenario S2.1: After I have started the program,
+When I call the search() function with a valid QUERY string
+And there is at least one match for my QUERY string
+Then it will return a torrent that is the first result in search query
+And then it will start downloading the returned torrent
+
+####Scenario S2.2: After I have started the program,
+When I call the search() function with an invalid QUERY string
+Then it will throw an error no torrent will be downloaded
+
+####Scenario S2.3: After I have started the program,
+When I call the search() function with a valid QUERY string
+And there are no matches for my QUERY string
+Then it will throw an error no torrent will be downloaded
