+
+## Installation
+
+Using [Cocoapods](https://cocoapods.org/) with Podfile:
+
+```ruby
+pod 'PushNotificationSimulation'
+```
+
+or using [Carthage](https://github.com/Carthage/Carthage) and add a line to `Cartfile`:
+
+```
+github "pwlkania/PushNotificationSimulation"
+```
+
+or Swift Package Manager (Xcode 11):
+
+Coming soon!
+
+## Requirements
+
+iOS 11.0
+
+## Initialization
+
+First of all, you need to modify your `AppDelegate.swift` file:
+
+Import `PushNotificationSimulation` framework (if needed):
+
+```swift
+import PushNotificationSimulation
+```
+
+Implement `PushNotificationSimulation` protocol:
+
+```swift
+#if DEBUG
+extension AppDelegate: PushNotificationSimulation { }
+#endif
+```
+
+Implement required property from `PushNotificationSimulation` protocol:
+
+```swift
+#if DEBUG
+weak var app: UIApplication?
+#endif
+```
+
+Assign `UIApplication` object to `app` property:
+
+```swift
+func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
+    // Your code...
+        
+    #if DEBUG
+    app = application
+    #endif
+        
+    // Your code...
+    return true
+}
+```
+
+Your `AppDelegate.swfit` file should look similar to this:

+
+## Usage
+
+Using breakpoints with debugger command (suggested approach) - example:
+
+```
+e simPush(payload: "{\"aps\":{\"alert\":{\"title\":\"Game Request\",\"subtitle\":\"Five Card Draw\",\"body\":\"Bob wants to play poker\"},\"category\":\"GAME_INVITATION\"},\"gameID\":\"12345678\"}", delay: 3)
+```
+

+
+You can also use `simPush(...)` global function directly in the code. However it might cause issues when code is not deactivated in production version of your application. Be careful.
