# Initialization

To initialize the SDK you have to add `MBAudience` to the array of plugins of `MBurger`.

```swift
import MBurgerSwift
import MBMessagesSwift

...

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    MBManager.shared.apiToken = "YOUR_API_TOKEN"
    MBManager.shared.plugins = [MBAudience()]

    return true
}
```

You can set a delegate when initializing the `MBAudience` plugin, the delegate will be called when audience data are sent successfully to the sever or if the sync fails

```swift
let audiencePlugin = MBAudience(delegate: [the delegate])
```
