Where in iOS 8 do I customize the notification centre? For some reason I cannot find Notification Centre section on my iPhone 6.

It's where you can set the today view to appear on lock screen, etc. I set it up a long time ago (probably in iOS 7), and I think there used to be a "Notification Centre" section in Settings. Now All I see is:

-Notifications (control notifications from apps)
-Control Centre
-Do Not Disturb

Where did it go? I searched online and tried to find it myself but it's taking too much time. Can anyone help?
Make certain your phone is unlocked and pull down the notification center.  When on the 'today' tab and unlocked, there is an 'edit' button at the bottom of the notification center that allows you to adjust what content is displayed and what order it is displayed.
