 SwiftyCam is a drop-in convenience framework. To create a Camera instance, create a new UIViewController subclass. Replace the UIViewController subclass declaration with SwiftyCamViewController:
 
-    class MyCameraViewController : SwiftyCamViewController
+```swift
+class MyCameraViewController : SwiftyCamViewController

 To use a SwiftyCamButton, simply create one and assign the delegate to your SwiftyCamViewController:
 
-    let captureButton = SwiftyCamButton(frame: buttonFrame)
-    captureButton.delegate = self
+```swift
+let captureButton = SwiftyCamButton(frame: buttonFrame)
+captureButton.delegate = self

 ### Manual:
 
 Capturing media with SwiftyCam is very simple. To capture a photo, simply call the takePhoto function:
 
-    takePhoto()
+```swift
+takePhoto()
+```    
 
 Capturing Video is just as easy. To begin recording video, call the startVideoRecording function:
 
-    startVideoRecording()
+```swift
+startVideoRecording()
+``` 
 
 To end the capture of a video, call the endVideoRecordingFunction:
 
-    endVideoRecording()
+```swift
+endVideoRecording()
+``` 
+
