+## Magazine app 
 
-Many apps (e.g. news and blogging) will need to get fresh content from a server as a form of a bundle. In this use case:
+This ServiceWorker demo webapp will allow a user to view a magazine app when offline, and gain some performance benefits by pulling the 'shell' of the app from a ServiceWorker cache. This should show how ServceWorker can be used to get fresh content from a server as a form of a bundle. Here are some detailed requirements:
 
-* The app 'shell' is held within a ServiceWorker cache
+* The magazine app 'shell' is held within a ServiceWorker cache
 * Some content is also held in a ServiceWorker cache or IndexedDB (this content was originally pulled from a server and displayed to the user on a previous session)
 * the app would first try to pull new content from the server
   * if succesful display to the user
-  * if unsuccessful the app takes the last piece of content from another ServiceWorker cache ''or'' from other storage and displays this instead.

-The user may benefit from some message to say "you have the most up to date content" (or something similar and less wordy!).
+The user may benefit from some message to say "you have the most up to date content" (or something similar and less wordy!). In this demo you should [1] register a ServiceWorker, [2] add the 'shell' into one ServiceWorker cache [3] add some content into another ServiceWorker cache, [3] use fetching to get content from the cache or server depending on whether a connection to the server was successful.
