+## Requirements
+
+- iOS 13.0+ / macOS 10.15+ / tvOS 13.0+
+- Xcode 11.0+
+- Swift 5.1+
+
+
+## Install
+
+### Swift Package Manager
+
+Open `Xcode`, go to `File -> Swift Packages -> Add Package Dependency` and enter `https://github.com/JWAutumn/ACarousel`
+
+You can also add `ACarousel` as a dependency to your `Package.swift`:
+```swift
+dependencies: [
+  .package(url: "https://github.com/JWAutumn/ACarousel", from: "0.1.2")
+]
+```
+
+### Manually
+
+[Download](https://github.com/JWAutumn/ACarousel/archive/main.zip) and open the project, drag the `ACarousel.swift` file into your own project.
+
+## Usage
+
+- Basic use: The parameters of `ACarousel` have default values, so you can simply pass in the data source and eat it ~
+```swift
+struct Item: Identifiable, Equatable {
+    let id = UUID()
+    let image: Image
+}
+
+let roles = ["Luffy", "Zoro", "Sanji", "Nami", "Usopp", "Chopper", "Robin", "Franky", "Brook"]
+
+struct ContentView: View {
+    
+    let items: [Item] = roles.map { Item(image: Image($0)) }
+    
+    var body: some View {

+## 要求
+
+- iOS 13.0+ / macOS 10.15+ / tvOS 13.0+
+- Xcode 11.0+
+- Swift 5.1+
+
+
+## 安装
+
+### Swift Package Manager
+
+打开 `Xcode`， 选择 `File -> Swift Packages -> Add Package Dependency`，输入 `https://github.com/JWAutumn/ACarousel`
+
+也可以将 `ACarousel` 作为依赖添加项到你的 `Package.swift` 中:
+```swift
+dependencies: [
+  .package(url: "https://github.com/JWAutumn/ACarousel", from: "0.1.2")
+]
+```
+
+### 手动安装
+
+[下载](https://github.com/JWAutumn/ACarousel/archive/main.zip)并打开项目，把 `ACarousel.swift` 文件拖入到你自己的项目当中。
+
+当然，你也可以根据特定需求修改代码。
+
+
+## 使用说明
+
+ - 基础使用：`ACarousel` 的参数有默认值，你只需要简单的传入数据源即可食用~
+```swift
+struct Item: Identifiable, Equatable {
+    let id = UUID()
+    let image: Image
+}
+
+let roles = ["Luffy", "Zoro", "Sanji", "Nami", "Usopp", "Chopper", "Robin", "Franky", "Brook"]
+
+struct ContentView: View {
+    
+    let items: [Item] = roles.map { Item(image: Image($0)) }
+    
+    var body: some View {
+        ACarousel(items) { item in
+            item.image
+                .resizable()
+                .scaledToFill()
+                .frame(height: 300)
+                .cornerRadius(30)
+        }
+        .frame(height: 300)
+    }
+}
+```
+
+- 自定义参数：根据自身需求，你可以修改相应的参数来自定义显示样式。
+```swift
+ /// ...
+
+struct ContentView: View {
+    
+    let items: [Item] = roles.map { Item(image: Image($0)) }
+    
+    var body: some View {
+        ACarousel(items,
+                  spacing: 10,
+                  headspace: 10,
+                  sidesScaling: 0.7,
+                  isWrap: true,
+                  autoScroll: .active(2)) { item in
+            item.image
+                .resizable()
+                .scaledToFill()
+                .frame(height: 300)
+                .cornerRadius(30)
+        }

+    }
+}
+```
