The Connector and the HTTP Transaction are now setup, now you have to add a Sequence : It will allow you to call your transaction, and extract to build the collection of objects you want for your news reader app.
Click on your project, this will display the Palette where you will have to Drag & Drop the "Generic Sequence" into the project itself. Name this Sequence "Get_CNN_Feed"
As a reminder, never forget to regularly save your project !
