 Create individual pages by creating instances of `OnboardingContentViewController`. Provide a title, body, image, text for an action button, and within the action block handle whatever you want to do when the users press the button.

 OnboardingContentViewController *firstPage = [OnboardingContentViewController contentWithTitle:@"Page Title" body:@"Page body goes here." image:[UIImage imageNamed:@"icon"] buttonText:@"Text For Button" action:^{
     // do something here when users press the button, like ask for location services permissions, register for push notifications, connect to social media, or finish the onboarding process
 }];
 ```

+```Swift
+let firstPage = OnboardingContentViewController(title: "Page Title", body: "Page body goes here.", image: UIImage(named: "icon"), buttonText: "Text For Button") { () -> Void in
+    // do something here when users press the button, like ask for location services permissions, register for push notifications, connect to social media, or finish the onboarding process
+    }
