 - Xcode 10.0+
 - Swift 4.0+
 ## Migration Guides
 - [SnapKit 3.0 Migration Guide](Documentation/SnapKit%203.0%20Migration%20Guide.md)
 ## Communication
 - If you **need help**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/snapkit). (Tag 'snapkit')
 - If you'd like to **ask a general question**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/snapkit).

 ## Installation
 ### CocoaPods
 [CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. You can install it with the following command:
 ```bash
 $ gem install cocoapods
 ```
 > CocoaPods 1.1.0+ is required to build SnapKit 4.0.0+.
 To integrate SnapKit into your Xcode project using CocoaPods, specify it in your `Podfile`:
 ```ruby
 source 'https://github.com/CocoaPods/Specs.git'
 platform :ios, '10.0'
 use_frameworks!
 target '<Your Target Name>' do
    pod 'SnapKit', '~> 5.7.0'
 end
 ```
 Then, run the following command:
 ```bash
 $ pod install
 ```
 ### Carthage
 [Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
 You can install Carthage with [Homebrew](http://brew.sh/) using the following command:
 ```bash
 $ brew update
 $ brew install carthage
 ```
 To integrate SnapKit into your Xcode project using Carthage, specify it in your `Cartfile`:
 ```ogdl
 github "SnapKit/SnapKit" ~> 5.0.0
 ```
 Run `carthage update` to build the framework and drag the built `SnapKit.framework` into your Xcode project.
 ### Swift Package Manager
 [Swift Package Manager](https://swift.org/package-manager/) is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.
 > Xcode 11+ is required to build SnapKit using Swift Package Manager.
 To integrate SnapKit into your Xcode project using Swift Package Manager, add it to the dependencies value of your `Package.swift`:
 ```swift
 dependencies: [
    .package(url: "https://github.com/SnapKit/SnapKit.git", .upToNextMajor(from: "5.0.1"))
 ]
 ```
 ### Manually
 If you prefer not to use either of the aforementioned dependency managers, you can integrate SnapKit into your project manually.
 ---
 ## Usage
 ### Quick Start
 ```swift
 import SnapKit
 class MyViewController: UIViewController {
    lazy var box = UIView()
    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.addSubview(box)
        box.backgroundColor = .green
        box.snp.makeConstraints { (make) -> Void in
           make.width.height.equalTo(50)
           make.center.equalTo(self.view)
        }
    }
 }
 ```
 ### Playground
 You can try SnapKit in Playground.
 **Note:**
 > To try SnapKit in playground, open `SnapKit.xcworkspace` and build SnapKit.framework for any simulator first.
