 ### Manually
 
 Just drag `KDCircularProgress.swift` into your project.
 
-### Carthage
-
-`Carthage` support is on To-do list.
+##Sample Code
+Below you can see code that creates and sets up a `KCircularProgress` instance. Which gives you a configuration that looks similar to the progress in the example images.
 
+```swift
+progress = KDCircularProgress(frame: CGRect(x: 0, y: 0, width: 300, height: 300))
+progress.startAngle = -90
+progress.progressThickness = 0.2
+progress.trackThickness = 0.6
+progress.clockwise = true
+progress.gradientRotateSpeed = 2
+progress.roundedCorners = false
+progress.glowMode = .forward
+progress.glowAmount = 0.9
+progress.set(colors: UIColor.cyan ,UIColor.white, UIColor.magenta, UIColor.white, UIColor.orange)
+progress.center = CGPoint(x: view.center.x, y: view.center.y + 25)
+view.addSubview(progress)
+```
 
 ## Properties
 
 ####progressColors: `[UIColor]`
 The colors used to generate the gradient of the progress. You can also set this using the variadic `setColors(UIColor...)` method. A gradient is used only if there is more than one color. A fill is used otherwise. The default is a white fill.
 
+------
+
 ####angle: `Int`
 The angle of the progress. Between 0 and 360 (inclusive). Simply change its value in order to change the visual progress of the component. Default is 0.
 
+------
+
 ####startAngle: `Int`
 The angle at which the progress will begin. Between 0 and 360 (inclusive), however you can pass any negative or positive values and the component will mod them automatically to the required range. Default is 0.
 
+------
+
 ####clockwise: `Bool`
 Clockwise if true, Counter-clockwise if false. Default is true.
 
+------
+
 ####roundedCorners: `Bool`
 When true, the ends of the progress track will be drawn with a half circle radius. Default is false.
 
+------
+
 ####gradientRotateSpeed: `CGFloat`
 Describes how many times the underlying gradient will perform a 2π rotation for each full cycle of the progress. Integer values recommended. Default is 0.
 
+------
+
 ####glowAmount: `CGFloat`
 The intensity of the glow. Between 0 and 1.0. Default is 1.0.
 
+------
+
 ####glowMode: `KDCircularProgressGlowMode`
-- **.Forward** - The glow increases proportionaly to the angle. No glow at 0 degrees and full glow at 360 degrees.
+- **.forward** - The glow increases proportionaly to the angle. No glow at 0 degrees and full glow at 360 degrees.
 
-- **.Reverse** - The glow increases inversely proportional to the angle. Full glow at 0 degrees and no glow at 360 degrees.
+- **.reverse** - The glow increases inversely proportional to the angle. Full glow at 0 degrees and no glow at 360 degrees.
 
-- **.Constant** - Constant glow.
+- **.constant** - Constant glow.
 
-- **.NoGlow** - No glow
+- **.noGlow** - No glow
 
-The default is **.Forward**
+The default is **.forward**
+
+------
 
 ####progressThickness: `CGFloat`
 The thickness of the progress. Between 0 and 1. Default is 0.4
 
+------
+
 ####trackThickness: `CGFloat`
 The thickness of the background track. Between 0 and 1. Default is 0.5
 
+------
+
 ####trackColor: `UIColor`
 The color of the background track. Default is `UIColor.blackColor()`.
 
+------
+
 ####progressInsideFillColor: `UIColor`
 The color of the center of the circle. Default is `UIColor.clearColor()`.
