 ## Usage

+### Controller
+
+To start your slideshow just instantiate `LightboxController`, set needed
+delegates and present it:
+
+
 ```swift
-<API>
+
+// Create an array of images.
+let images = [
+  LightboxImage(imageURL: URL(string: "https://cdn.arstechnica.net/2011/10/05/iphone4s_sample_apple-4e8c706-intro.jpg")!),
+  LightboxImage(
+    image: UIImage(named: "photo1")!,
+    text: "This is an example of a remote image loaded from URL"
+  ),
+  LightboxImage(
+    image: UIImage(named: "photo2")!,
+    text: "",
+    videoURL: URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
+  ),
+  LightboxImage(
+    image: UIImage(named: "photo3")!,
+    text: "This is an example of a local image."
+  )
+]
+
+// Create an instance of LightboxController.
+let controller = LightboxController(images: images)
+
+// Set delegates.
+controller.pageDelegate = self
+controller.dismissalDelegate = self
+
+// Use dynamic background.
+controller.dynamicBackground = true
+
+// Present your controller.
+present(controller, animated: true, completion: nil)
+```
+
+### Delegates
+
+Use `LightboxControllerPageDelegate` if you want to be notified about page
+navigation changes.
+
+```swift
+extension ViewController: LightboxControllerPageDelegate {
+
+  func lightboxController(_ controller: LightboxController, didMoveToPage page: Int) {
+    print(page)
+  }
+}
+```
+
+Use `LightboxControllerDismissalDelegate` to be notified when controller is
+about to be dismissed. Please note that `LightboxController` dismisses itself
+if it was presented initially.
+
+```swift
+extension ViewController: LightboxControllerDismissalDelegate: class {
+
+  func lightboxControllerWillDismiss(_ controller: LightboxController) {
+    // ...
+  }
+}
+```
+
+### Image loading
+
+By default images are loaded using `sendAsynchronousRequest` method of
+`NSURLConnection`. But it's easy to change this behavior using **Lightbox**
+configuration.
+
+```swift
+LightboxConfig.loadImage = {
+  imageView, URL, completion in
+  // Custom image loading
+}
+```
+
+### Video
+
+**Lightbox** has video support out of the box. Configure video by using `videoURL`:
+
+```swift
+LightboxImage(
+  image: UIImage(named: "photo2")!,
+  text: "",
+  videoURL: NSURL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
+)
+```
+
+Override video handling if needed:
+
+```swift
+LightboxConfig.handleVideo = { from, videoURL in
+  // Custom video handling
+  let videoController = AVPlayerViewController()
+  videoController.player = AVPlayer(url: videoURL)
+
+  from.present(videoController, animated: true) {
+    videoController.player?.play()
+  }
+}
+```
+
+### Configuration
+
+Configure text, colors, fonts of UI elements by overriding the static
+variables in the **Lightbox** [configuration](https://github.com/hyperoslo/Lightbox/blob/master/Source/LightboxConfig.swift) struct. As an example:
+
+```swift
+LightboxConfig.CloseButton.image = UIImage(named: ImageList.Lightbox.closeButton)
+LightboxConfig.CloseButton.textAttributes = TextAttributes.Lightbox.closeButton
+LightboxConfig.CloseButton.text = "Finish"
+
+LightboxConfig.DeleteButton.image = UIImage(named: ImageList.Lightbox.deleteButton)
+LightboxConfig.DeleteButton.textAttributes = TextAttributes.Lightbox.deleteButton
+LightboxConfig.DeleteButton.text = "Delete"
+
+LightboxConfig.InfoLabel.ellipsisText = "ShowMore"
 ```
