+
+#### [Swift Package Manager for Apple platforms](https://developer.apple.com/documentation/xcode/adding_package_dependencies_to_your_app)
+
+Select Xcode menu `File > Swift Packages > Add Package Dependency` and enter repository URL with GUI.  
+```
+Repository: https://github.com/lixiang1994/UIAdapter
+```
+
+#### [Swift Package Manager](https://swift.org/package-manager/)
+
+Add the following to the dependencies of your `Package.swift`:
+```swift
+.package(url: "https://github.com/lixiang1994/UIAdapter.git", from: "version")
+```
+
+## Usage
+
+First make sure to import the framework:
+
+```swift
+import UIAdapter
+```
+
+Here are some usage examples. All devices are also available as simulators:
+
+
+### Auto
+
+
+AutoLayout (SnapKit): 
+
+```swift
+private func setupLayout() {
+    cardView.snp.makeConstraints { (make) in
+	make.top.equalTo(16.auto())
+	make.left.right.equalToSuperview().inset(15.auto())
+	make.bottom.equalTo(-26.auto())
+    }
+
+    lineView.snp.makeConstraints { (make) in
+	make.left.right.equalToSuperview().inset(15.auto())
+	make.top.equalTo(titleLabel.snp.bottom)
+	make.height.equalTo(1)
+    }
+
+    titleLabel.snp.makeConstraints { (make) in
+        make.top.equalToSuperview()
+        make.left.equalTo(15.auto())
+        make.height.equalTo(48.auto())
+    }
+
+    stateLabel.snp.makeConstraints { (make) in
+        make.top.equalTo(lineView).offset(10.auto())
+        make.left.equalTo(15.auto())
+        make.height.equalTo(15.auto())
+    }
+}
+```
+
+Property (Then):
+
+```swift
+private lazy var cardView = UIView().then {
+    $0.cornerRadius = 6.auto()
+    $0.backgroundColor = .white
+}
+
+private lazy var lineView = UIView().then {
+    $0.backgroundColor = .hex("000000", alpha: 0.05)
+}
+
+private lazy var titleLabel = UILabel().then {
+    $0.textColor = .black
+    $0.font = .systemFont(ofSize: 20.auto(), weight: .medium)
+}
+
+private lazy var stateLabel = UILabel().then {
+    $0.textColor = .gray
+    $0.font = .systemFont(ofSize: 12.auto(), weight: .medium)
+}
+```
+
+Storyboard / Xib:

+![Constraint](Resources/Storyboard%20Constraint.png)
+![UILabel Font](Resources/Storyboard%20Label%20Font.png)
+
+### Screen
+
+e.g.
+
+```swift
+// default other screen numberOfLines = 0
+// 3.5 inches screen numberOfLines = 1
+// 4.0 inches screen numberOfLines = 2
+label.numberOfLines = 0.screen.inch(._3_5, is: 1).inch(._4_0, is: 2).value
+```
+
+
+```swift
+// default other screen numberOfLines = 0
+// width 320 screen numberOfLines = 1
+// width 375 inches screen numberOfLines = 2
+label.numberOfLines = 0.screen.width(._320, is: 1).width(._375, is: 2).value
+```
+
+
+```swift
+print("this is " +
+    "default".screen
+    .width(._320, is: "width 320")
+    .width(._375, is: "width 375")
+    .height(._844, is: "height 844")
+    .height(._812, is: "height 812")
+    .inch(._4_7, is: "4.7 inches")
+    .inch(._5_8, is: "5.8 inches")
+    .inch(._6_5, is: "6.5 inches")
+    .level(.compact, is: "screen 3: 2")
+    .level(.regular, is: "screen 16: 9")
+    .level(.full, is: "screen 19.5: 9")
+    .value
+)
+```
