+## 中文版本
+
+本仓库包含 *The Swift Programming Language* (缩写为 TSPL) 的源代码，
+该文档发布在 [docs.swift.org][published] 上，
+并使用 [Swift-DocC][docc] 构建。
+
+本仓库包括 TSPL 的最新版本，以及对应不同 Swift 版本的简体中文翻译。
+
+## 构建
+
+克隆此仓库并在仓库根目录运行 `docc preview swift-6-beta-translation.docc`。
+
+运行 DocC 后，打开 `docc` 输出的链接，即可在浏览器中显示本地预览。
+
+## 当前状态
+
+- The Swift Programming Language 的最新英文版本。[最新提交: 11a2b29][11a2b29]
+- 对应的简体中文翻译 (进行中和已归档)：
+  - Swift 6 beta (当前正在翻译)
+  - Swift 5.x 及更早版本 (可在 [GitBook][legacy-documentations] 上阅读)
+
+## 如何贡献
+
+1. 首先，将此仓库 fork 到您的账户。在 issues 中认领标记为 `Swift x translation` 的翻译任务。在您 fork 的仓库中创建与 issue 对应的分支，将源分支设置为当前正在翻译的 Swift 版本 (例如，swift-6-beta-translation)。
+
+2. 通过从 Swift.org 下载 toolchain 或安装 Xcode 来安装 `docc` 命令行工具。
+
+> 注意：
+>
+> 如果您通过从 Swift.org 下载 toolchain 安装了 DocC，
+> `docc` 位于 toolchain 安装路径下的 `usr/bin/` 目录中。
+> 确保您的 shell 的 `PATH` 环境变量包含该目录。
+>
+> 如果您通过下载 Xcode 安装了 DocC，
+> 请运行 `xcrun docc preview swift-6-beta-translation.docc`。
+
+3. 按照下面的术语表和 [SwiftGG 排版指南][swiftgg-style-guide] 将原始 Markdown 文件的内容替换为您的中文翻译。通过 Pull Request 提交您的翻译。经 SwiftGG 成员验证后，将合并到当前的翻译分支。
