 ## UIViewController+KNSemiModal Category
 
-UIViewController+KNSemiModal is an effort to make a replica of **semi-modal view with pushed-back stacked animation** found in the beautiful [Park Guides by National Geographic](http://itunes.apple.com/us/app/national-parks-by-national/id518426085?mt=8) app. You can see this original semi-modal view below.
-
-This library (ARC) is designed as a Category to UIViewController so you don't have to subclass and you can simply drop in any project and it will just work!

-Download a demo clip [here](https://github.com/kentnguyen/KNSemiModalViewController/blob/master/Docs/KNSemiModalDemo.mov?raw=true) (1.3MB, .mov)
-
-### Features
-* Works with bare UIViewController
-* Works with UIViewController contained inside UINavigationController
-* Works with UIViewController contained inside UINavigationController, contained inside UITabbarController
-* Auto handling of modal frame size
-* Auto handling of touch area for dismissal
-* Resizable after presenting so that keyboard related interactions are possible
-* Easy to understand and very small code base, only 2 files
-* Trivial to implement as subclass
-* Landscape support (not during presentation)
-* Only use basic CAAnimation
-* iPad support (experimental)
-* Minimum iOS 5.0 (if you need 4.x support, use older commits before Jan 2013)
-
-### Optional parameters
-
-- animation duration
-- parent alpha
-- optional push-back
-- shadow opacity
-- disabling the cancel action
-- transition style: slide up, fade
-
-Easily extend this to anything you would want to make configurable. Feel free to submit pull requests.
-
-### Installation / How to use
-* Copy 4 files in `Source` folder to your project
-* Add `QuartzCore.framework` to your project
-* `#import "UIViewController+KNSemiModal.h"` in your ViewController
-* Call `[self presentSemiModalView:myView]`
-* Call `[self dismissSemiModalView]` either from parent/presenting or child/presented controller
