+```
 
+## Usage
+
+1) ``` import PreviewTransition ```
+
+2) Create UITableViewController inherit, inheriting from ```PTTableViewController```
+
+3) Add UITableViewDelegate methods
+
+```swift
+public override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
+    return <RowsCount>
+}
+
+public override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
+    return tableView.dequeueReusableCellWithIdentifier(<CellIdentifier>, forIndexPath: indexPath)
+}
+```
+
+4) add a ParallaxCell
+
+storyboards:
+create a cell and inherit from ```ParallaxCell```; don't forget set the identifier ```<CellIdentifier>```
+
+or programmatically:
+register a cell in viewDidLoad ```tableView.registerClass(ParallaxCell, forCellReuseIdentifier:<CellIdentifier>)```
+
+5) set cell height
+
+6) create image names (image sizes must be equal to screen size or bigger)
+
+```swift
+let images = [image_name, image_name, image_name, image_name, image_name] // image names
+```
+
+7) set image and text for ParallaxCell
+
+```swift
+public override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
+
+    guard let cell = cell as? ParallaxCell else {
+      return
+    }
+
+    let imageName = images[indexPath.row]
+
+    if let image = UIImage(named: imageName) {
+      cell.setImage(image, title: <SetText>)
+    }
+}
+```
+your tableViewController should look like [DemoTableViewController](https://github.com/Ramotion/preview-transition/blob/master/PreviewTransitionDemo/PreviewTransitionDemo/ViewController/DemoTableViewController.swift)
+
+Method ```public override func tableView(tableView: didSelectRowAtIndexPath indexPath:)``` we will add later. (step 10)
+
+8) Create UIViewController, inheriting from ```PTDetailViewController```
+
+9) Add action for backButton and call ```popViewController()```
+
+```swift
+func backButtonHandler() {
+    popViewController()
+}
+```
+
+10) Push this UIViewController in UITableViewController. Add method
+
+```swift
+public override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
+
+  // create viewController
+  let <YourViewController> = storyboard?.instantiateViewControllerWithIdentifier(<identifier>)
+  if case let viewController as <YourViewController> = viewController {
+     pushViewController(viewController)
+  }
+}
+```
+
+11) Configure UINavigationBar
+
+```swift
+// transparent background
+UINavigationBar.appearance().setBackgroundImage(UIImage(), forBarMetrics: .Default)
+UINavigationBar.appearance().shadowImage = UIImage()
+UINavigationBar.appearance().translucent = true
+UINavigationBar.appearance().tintColor = .whiteColor()
+
+// set font
+if let font = UIFont(name: <Font name> , size: 18) {
+      UINavigationBar.appearance().titleTextAttributes = [
+        NSForegroundColorAttributeName : UIColor.whiteColor(),
+        NSFontAttributeName : font
+      ]
+}
+```
