+
+## Requirements
+
+* iOS 7.0+ 
+* ARC
+
+## Installation
+
+### CocoaPods
+
+[CocosPods](http://cocosPods.org) is the recommended method to install SLPagingView.
+
+Add the following line to your Podfile:
+
+```ruby
+pod 'SLPagingViewSwift'
+```
+
+And run
+```ruby
+pod install
+```
+
+### Manual
+
+Import SLPagingView folder into your project.
+
+
+## How to use
+
+Easy to implement:
+
+```swift
+
+	// Make views for the navigation bar
+    var img1 = UIImage(named: "gear")
+	img1 = img1?.imageWithRenderingMode(.AlwaysTemplate)
+	var img2 = UIImage(named: "profile")
+	img2 = img2?.imageWithRenderingMode(.AlwaysTemplate)
+	var img3 = UIImage(named: "chat")
+	img3 = img3?.imageWithRenderingMode(.AlwaysTemplate)
+
+    var items = [UIImageView(image: img1), UIImageView(image: img2), UIImageView(image: img3)]
+	var controllers = [ctr1, ctr2, ctr3]
+	controller = SLPagingViewSwift(items: items, controllers: controllers, showPageControl: false)
+
+````
+
+Then you can make your own behaviors:
+
+```swift
+
+	// Tinder Like
+    controller?.pagingViewMoving = ({ subviews in
+		for v in subviews {
+			var lbl = v as UIImageView
+            var c = gray
+
+			if(lbl.frame.origin.x > 45 && lbl.frame.origin.x < 145) {
+				c = self.gradient(Double(lbl.frame.origin.x), topX: Double(46), bottomX: Double(144), initC: orange, goal: gray)
+			}
+			else if (lbl.frame.origin.x > 145 && lbl.frame.origin.x < 245) {
+				c = self.gradient(Double(lbl.frame.origin.x), topX: Double(146), bottomX: Double(244), initC: gray, goal: orange)
+			}
+			else if(lbl.frame.origin.x == 145){
+				c = orange
+			}
+			lbl.tintColor = c
+		}
+	})
+
+````
+
+##Other example
+
+Twitter like behaviors
+
+```swift
+
+	// Twitter Like
+	controller?.pagingViewMovingRedefine = ({ scrollView, subviews in
+		var i = 0
+		var xOffset = scrollView.contentOffset.x
+		for v in subviews {
+			var lbl = v as UILabel
+			var alpha = CGFloat(0)
+
+			if(lbl.frame.origin.x > 45 && lbl.frame.origin.x < 145) {
+				alpha = 1.0 - (xOffset - (CGFloat(i)*320.0)) / 320.0
+			}
+			else if (lbl.frame.origin.x > 145 && lbl.frame.origin.x < 245) {
+				alpha = (xOffset - (CGFloat(i)*320.0)) / 320.0 + 1.0
+			}
+			else if(lbl.frame.origin.x == 145){
+				alpha = 1.0
+			}
+			lbl.alpha = CGFloat(alpha)
+			i++
+		}
+	})
+````
+
+##API
+
+###Set current page
+
+If you want to changed the default page control index (or whatever) you can do it calling:
+
+```swift
+
+	func setCurrentIndex(index: NSInteger, animated: Bool)
+````
+
+###Navigation items style
+
+<img src="https://raw.githubusercontent.com/StefanLage/SLPagingView/master/Demos/TinderLike/navigation_style.gif" height="440" width="250" style="margin-left:50px;">
+
+You can easily customized the navigation items setting up:
+
+
+```swift
+
+	var navigationSideItemsStyle: SLNavigationSideItemsStyle
+````
+
+
+By using one of these values:
+
+
+```swift
+
+	enum SLNavigationSideItemsStyle: Int {
+    	case SLNavigationSideItemsStyleOnBounds = 40
+	    case SLNavigationSideItemsStyleClose = 30
+    	case SLNavigationSideItemsStyleNormal = 20
+	    case SLNavigationSideItemsStyleFar = 10
+    	case SLNavigationSideItemsStyleDefault = 0
+	    case SLNavigationSideItemsStyleCloseToEachOne = -40
+	}
+````
