Cloud kit Dasboard

Hi,


I am a very very new newbie..


I have written and App to store data to the cloud and it works fine in Development.


I have uploaded it to Test Flight and Apple has approved it.


However I have no idea what to do next to make the App work with iCloud so the user can store their own data on their own iCloud account.


I there something I have to do in the app or the Cloud Kit Dash Board?


Please help.


Very new to this.


Thanks..


Craig.
