No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?"

These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided.

+
+You can show a floating panel over UINavigationController from the containnee view controllers as a modality of `.overCurrentContext` style.
+
+NOTE: FloatingPanelController has the custom presentation controller. If you would like to customize the presentation/dismissal, please see [FloatingPanelTransitioning](https://github.com/SCENEE/FloatingPanel/blob/feat-modality/Framework/Sources/FloatingPanelTransitioning.swift).
+
 ## Usage

-### Move a positon with an animation
-
-Move a floating panel to the top and middle of a view while opening and closeing a search bar like Apple Maps.
+### Show/Hide a floating panel in a view with your view hierarchy

 ```swift
-    func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
-        ...
-        fpc.move(to: .half, animated: true)
-    }
+// Add the controller and the managed views to a view controller.
+// From the second time, just call `show(animated:completion)`.
+view.addSubview(fpc.view)
+fpc.view.frame = view.bounds // MUST
+parent.addChild(fpc)

-    func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
-        ...
-        fpc.move(to: .full, animated: true)
-    }
-```
+// Show a floating panel to the initial position defined in your `FloatingPanelLayout` object.
+fpc.show(animated: true) {

-### Make your contents correspond with FloatingPanel behavior
+    // Only for the first time
+    self.didMove(toParent: self)
+}

-```swift
-class ViewController: UIViewController, FloatingPanelControllerDelegate {
-    ...
-    func floatingPanelWillBeginDragging(_ vc: FloatingPanelController) {
-        if vc.position == .full {
-            searchVC.searchBar.showsCancelButton = false
-            searchVC.searchBar.resignFirstResponder()
-        }
-    }
+...

-    func floatingPanelDidEndDragging(_ vc: FloatingPanelController, withVelocity velocity: CGPoint, targetPosition: FloatingPanelPosition) {
-        if targetPosition != .full {
-            searchVC.hideHeader()
-        }
-    }
-    ...
+// Hide it
+fpc.hide(animated: true) {
+
+    // Remove it if needed
+    self.willMove(toParent: nil)
+    self.view.removeFromSuperview()
+    self.removeFromParent()
 }
 ```

-### Support your landscape layout with a `FloatingPanelLayout` object
+NOTE: `FloatingPanelController` wraps `show`/`hide` with `addPanel`/`removePanelFromParent` for easy-to-use. But `show`/`hide` are more convenience for your app.
+
+### Customize the layout with `FloatingPanelLayout` protocol
+
+#### Change the initial position and height

 ```swift
 class ViewController: UIViewController, FloatingPanelControllerDelegate {
    ...
    func floatingPanel(_ vc: FloatingPanelController, layoutFor newCollection: UITraitCollection) -> FloatingPanelLayout? {

-### Modify your floating panel's interaction with a `FloatingPanelBehavior` object
+#### Use Intrinsic height layout
+
+1. Lay out your content View with the intrinsic height size. For example, see "Detail View Controller scene"/"Intrinsic View Controller scene" of [Main.storyboard](https://github.com/SCENEE/FloatingPanel/blob/master/Examples/Samples/Sources/Base.lproj/Main.storyboard). The 'Stack View.bottom' constraint determines the intrinsic height.

 ### Create an additional floating panel for a detail

 ```swift
-class ViewController: UIViewController, FloatingPanelControllerDelegate {
-    var searchPanelVC: FloatingPanelController!
-    var detailPanelVC: FloatingPanelController!
+override func viewDidLoad() {
+    // Setup Search panel

-    }
-    ...
+    self.detailPanelVC.addPanel(toParent: self)

 ```

+### Move a position with an animation
+
+In the following example, I move a floating panel to full or half position while opening or closing a search bar like Apple Maps.
+
+```swift
+func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
+    ...
+    fpc.move(to: .half, animated: true)
+}
+
+func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
+    ...
+    fpc.move(to: .full, animated: true)
+}
+```
+
+### Work your contents together with a floating panel behavior
+
+```swift
+class ViewController: UIViewController, FloatingPanelControllerDelegate {
+    ...
+    func floatingPanelWillBeginDragging(_ vc: FloatingPanelController) {
+        if vc.position == .full {
+            searchVC.searchBar.showsCancelButton = false
+            searchVC.searchBar.resignFirstResponder()
+        }
+    }
+
+    func floatingPanelDidEndDragging(_ vc: FloatingPanelController, withVelocity velocity: CGPoint, targetPosition: FloatingPanelPosition) {
+        if targetPosition != .full {
+            searchVC.hideHeader()
+        }
+    }
+}
+```
+
+## Notes
+
+### 'Show' or 'Show Detail' Segues from `FloatingPanelController`'s content view controller
+
+'Show' or 'Show Detail' segues from a content view controller will be managed by a view controller(hereinafter called 'master VC') adding a floating panel. Because a floating panel is just a subview of the master VC(except for modality).
+
+`FloatingPanelController` has no way to manage a stack of view controllers like `UINavigationController`. If so, it would be so complicated and the interface will become `UINavigationController`. This component should not have the responsibility to manage the stack.
+
+By the way, a content view controller can present a view controller modally with `present(_:animated:completion:)` or 'Present Modally' segue.
+
+However, sometimes you want to show a destination view controller of 'Show' or 'Show Detail' segue with another floating panel. It's possible to override `show(_:sender)` of the master VC!
+
+Here is an example.
+
+```swift
+class ViewController: UIViewController {
+    var fpc: FloatingPanelController!
+    var secondFpc: FloatingPanelController!
+
+    ...
+    override func show(_ vc: UIViewController, sender: Any?) {
+        secondFpc = FloatingPanelController()
+
+        secondFpc.set(contentViewController: vc)
+
+        secondFpc.addPanel(toParent: self)
+    }
+}
+```
+
+A `FloatingPanelController` object proxies an action for `show(_:sender)` to the master VC. That's why the master VC can handle a destination view controller of a 'Show' or 'Show Detail' segue and you can hook `show(_:sender)` to show a secondary floating panel set the destination view controller to the content.
+
+It's a great way to decouple between a floating panel and the content VC.
+
+### FloatingPanelSurfaceView's issue on iOS 10
+
+* On iOS 10, `FloatingPanelSurfaceView.cornerRadius` isn't not automatically masked with the top rounded corners  because of `UIVisualEffectView` issue. See https://forums.developer.apple.com/thread/50854. 
+So you need to draw top rounding corners of your content.  Here is an example in Examples/Maps.
+```swift
+override func viewDidLayoutSubviews() {
+    super.viewDidLayoutSubviews()
+    if #available(iOS 10, *) {
+        visualEffectView.layer.cornerRadius = 9.0
+        visualEffectView.clipsToBounds = true
+    }
+}
+```
+* If you sets clear color to `FloatingPanelSurfaceView.backgroundColor`, please note the bottom overflow of your content on bouncing at full position. To prevent it, you need to expand your content. For example, See Example/Maps App's Auto Layout settings of `UIVisualEffectView` in Main.storyboard.
