 ### Working with UITableView & UICollectionView
 
 Working with a collections classes is not difficult. In the `Example` folder you can find an implementation. However, I will give a couple of tips for making the table look better.

 Please, also use `SPStorkController.scrollViewDidScroll` function in scroll delegate for more interactiveness with your collection or table view.
 
+### Confirm
+
+For confirm closing by swipe, tap around, close button and indicator use `SPStorkControllerConfirmDelegate`. Implenet protocol:
+
+```swift
+@objc public protocol SPStorkControllerConfirmDelegate: class {
+    
+    var needConfirm: Bool { get }
+    
+    func confirm(_ completion: @escaping (_ isConfirmed: Bool)->())
+}
+```
+
+and set `confirmDelegate` property to object, which protocol impleneted. Function `confirm` call if `needConfirm` return true. Pass `isConfirmed` with result. Best options use `UIAlertController` with `.actionSheet` style for confirmation.
+
+If you use custom buttons, in the target use this code:
+
+```swift
+SPStorkController.dismissWithConfirmation(controller: self, completion: nil)
+```
+
+It call `confirm` func and check result of confirmation. See example project for more details.

 ### Delegate
 
 You can check events by implement `SPStorkControllerDelegate` and set delegate for `transitionDelegate`:
