+# Documentation Development Guide
+
+## 📘 Introduction
+We use VitePress to develop and manage our documentation. This guide explains how to add, edit, preview, and build docs in this project with a consistent structure for both Chinese and English.
+
+## 🗂️ Project Structure
+```text
+/doc
+  ├─ package.json
+  └─ docs
+      ├─ .vitepress
+      │   └─ config.mts        # Site & sidebar configuration
+      ├─ cn                    # Chinese docs
+      ├─ en                    # English docs
+      ├─ assets                # Site assets
+      ├─ public                # Static public assets
+      └─ index.md
+```
+
+## 📦 Install Dependencies
+From the `doc` directory:
+
+```bash
+pnpm install
+```
+
+## 💻 Local Development
+Start the dev server:
+
+```bash
+pnpm vitepress dev docs
+```
+
+After successfully start, visit:
+
+- `http://localhost:5173/doc`
+
+## ✍️ Add or Edit Docs
+- Put Chinese docs under `doc/docs/zh` and English docs under `doc/docs/en`.
+- Use kebab-case file names, e.g., `getting-started.md`.
+- Routes map to file paths, e.g.:
+  - `doc/docs/zh/foo/bar.md` → `/zh/foo/bar`
+  - `doc/docs/en/foo/bar.md` → `/en/foo/bar`
+
+## 🧭 Sidebar and Navigation
+- The sidebar is configured in `doc/docs/.vitepress/config.mts`.
+- An entry for this guide has been added right after "Backend Development": `/zh/docs-development` (Chinese) and `/en/docs-development` (English).
+- For new pages, add links in the corresponding locale's sidebar and ensure paths match the file locations.
+
+## 🖼️ Assets
+- Prefer `doc/docs/public` for shared assets and reference them using absolute paths, e.g., `/images/logo.png`.
+- Page-specific assets can live alongside the page and be referenced via relative paths.
+
+## ✅ Build and Validate
+Before committing, build the docs to check for dead links and other issues:
+
+```bash
+pnpm run docs:build
+```
+
+Preview the production build locally:
+
+```bash
+pnpm run docs:preview
+```

+# 文档开发指南
+
+## 📘 简介
+我们使用 VitePress 进行文档的开发与管理，统一组织中英文内容、侧边栏与导航配置，支持本地开发预览与构建发布。本文档指导你如何在本项目中新增、编辑与校验文档。
+
+## 🗂️ 目录结构
+```text
+/doc
+  ├─ package.json
+  └─ docs
+      ├─ .vitepress
+      │   └─ config.mts        # 站点与侧边栏配置
+      ├─ zh                    # 中文文档目录
+      ├─ en                    # 英文文档目录
+      ├─ assets                # 站点资源
+      ├─ public                # 公共静态资源
+      └─ index.md
+```
+
+## 📦 安装依赖
+在 `doc` 目录下执行：
+
+```bash
+pnpm install
+```
+
+## 💻 本地开发
+启动本地开发服务器：
+
+```bash
+pnpm vitepress dev docs
+```
+
+启动成功后，请通过以下地址访问：
+
+- `http://localhost:5173/doc`
+
+## ✍️ 新增与编辑文档
+- 中文文档放在 `doc/docs/zh`，英文文档放在 `doc/docs/en`。
+- 文件命名建议使用小写短横线（kebab-case），例如：`getting-started.md`。
+- 页面路径与文件路径一一对应，例如：
+  - `doc/docs/zh/foo/bar.md` 将通过 `/zh/foo/bar` 访问；
+  - `doc/docs/en/foo/bar.md` 将通过 `/en/foo/bar` 访问。
+
+## 🧭 配置侧边栏与导航
+- 侧边栏配置位于 `doc/docs/.vitepress/config.mts`。
+- 若新增页面，请在对应语言的 `sidebar` 中添加链接项，注意与文件路径一致。
+
+## 🖼️ 使用资源
+- 推荐将公共图片放到 `doc/docs/public`，通过绝对路径引用，例如：`/images/logo.png`。
+- 也可以将与页面紧密相关的资源放入同级目录，并使用相对路径引用。
+
+## ✅ 构建与校验
+在正式提交前请进行构建，以检查死链（dead links）等问题：
+
+```bash
+pnpm run docs:build
+```
+
+构建成功后可本地预览：
+
+```bash
+pnpm run docs:preview
+```
