+### Edge cases
+
+When you need to present few alerts in a row you should set `shouldDismissAutomatically` flag to `false` and add action AFTER view controller initialization to be able to capture alert instance in action handler's closure.
+
+```swift
+
+let viewModel = Alert(
+    title: "Your Title",
+    message: "Your Message"
+)
+let alert = AlertViewController(viewModel: viewModel)
+alert.shouldDismissAutomatically = false
+
+let cancelAction = Alert.Action(title: "Cancel", style: .primary) { [weak alert] _ in
+    alert?.dismiss(animated: true) {
+        // present something else
+    }
+}
+alert.addAction(cancelAction)
+
+let confirmAction = Alert.Action(title: "Confirm", style: .default) { [weak alert] _ in
