+# ESEngine Editor
+
+ESEngine 可视化编辑器，基于 Tauri 2.x + React 18 构建的跨平台桌面应用。
+
+A cross-platform desktop visual editor built with Tauri 2.x + React 18.
+
+## Prerequisites | 前置条件
+
+Before running the editor, ensure you have the following installed:
+
+运行编辑器前，请确保已安装以下环境：
+
+- **Node.js** >= 18.x
+- **pnpm** >= 10.x
+- **Rust** >= 1.70 (for Tauri)
+- **Platform-specific dependencies**:
+  - **Windows**: Microsoft Visual Studio C++ Build Tools
+  - **macOS**: Xcode Command Line Tools (`xcode-select --install`)
+  - **Linux**: `webkit2gtk`, `libgtk-3-dev`, `libappindicator3-dev` (see [Tauri prerequisites](https://tauri.app/v1/guides/getting-started/prerequisites))
+
+## Quick Start | 快速启动
+
+### 1. Clone and Install | 克隆并安装
+
+```bash
+git clone https://github.com/esengine/esengine.git
+cd esengine
+pnpm install
+```
+
+### 2. Build Dependencies | 构建依赖
+
+Build the required packages before running the editor:
+
+在运行编辑器前，先构建所需的依赖包：
+
+```bash
+# Build all editor dependencies
+pnpm --filter @esengine/editor-app... build
+```
+
+### 3. Run in Development Mode | 开发模式运行
+
+```bash
+cd packages/editor/editor-app
+pnpm tauri:dev
+```
+
+This will:
+1. Build the editor SDK (`@esengine/editor-runtime`)
+2. Copy engine modules to the editor
+3. Start Tauri in development mode with hot-reload
+
+这将会：
+1. 构建编辑器 SDK (`@esengine/editor-runtime`)
+2. 复制引擎模块到编辑器
+3. 以热重载的开发模式启动 Tauri
+
+### 4. Build for Production | 生产构建
+
+```bash
+cd packages/editor/editor-app
+pnpm tauri:build
+```
+
+The built application will be in `src-tauri/target/release/`.
+
+构建的应用程序将位于 `src-tauri/target/release/` 目录。
+
+## Available Scripts | 可用脚本
+
+| Script | Description |
+|--------|-------------|
+| `pnpm tauri:dev` | Run editor in development mode with hot-reload |
+| `pnpm tauri:build` | Build production application |
+| `pnpm build` | Build web assets only (without Tauri) |
+| `pnpm build:sdk` | Build editor-runtime SDK |
+| `pnpm copy-modules` | Copy engine modules to editor |
+| `pnpm bundle:runtime` | Bundle runtime for production |
