 ## Delegation
 
+Delegation is a design pattern that enables a class to hand off (or “delegate”) some of its responsibilities to an instance of another class.
+
+### Example
+
+Create a protocol 
+
+```swift
+protocol SomeProtocol {
+    func reload()
+}
+```
+
+Create a delegate 
 ```swift
 weak var delegate: SomeProtocol?
 ```
+
