+### 2. 打包 wheel（产物输出到根目录 `dist/`）📦
 
-请确保你已安装 Python 3.10 或以上版本。
+如需自行打包发布，请按以下顺序执行：先构建前端，再构建后端 wheel，并将产物输出到项目根目录 `dist/`（与 `backend/` 同级）。
+
+```bash
+# 1) 构建前端静态资源
+cd frontend
+npm install
+npm run build
+
+# 2) 构建后端 wheel，并输出到根目录 dist/
+cd ../backend
+uv build --out-dir ../dist
+```
+
+构建完成后，wheel 位于项目根目录 `dist/`，例如 `dist/dataclaw-0.1.0-py3-none-any.whl`。
+
+### 3. 标准部署（推荐，无需 Node.js）📦
+
+请确保你已安装 Python 3.11 或以上版本。发布包已内置前端静态资源，生产部署无需安装 Node.js。
+
+```bash
+# 建议先创建虚拟环境
+python -m venv .venv
+source .venv/bin/activate
+
+# 安装 DataClaw（示例：安装根目录 dist 下的 wheel）
+pip install ./dist/dataclaw-*.whl
+
+# 启动服务（默认 http://127.0.0.1:8000）
+dataclaw start
+```
+
+常用服务控制命令：
+
+```bash
+# 查看运行状态
+dataclaw status
+
+# 自定义监听地址/端口
+dataclaw start --host 0.0.0.0 --port 8000
+
+# 停止服务
+dataclaw stop
+```
+
+可选环境变量：
+
+```bash
+export DATA_ROOT=/absolute/path/to/data
+```
+
+若未设置，默认使用仓库根目录下的 `data/`。服务状态文件与日志默认位于 `DATA_ROOT/run/`。

-### 2. Backend Setup 🐍
+### 2. Standard Deployment (Recommended, No Node.js Required) 📦
 
-Ensure you have Python 3.10+ installed.
+Ensure you have Python 3.11+ installed. The pre-built React frontend is bundled in the Python wheel, so you don't need Node.js for production deployment.
+
+#### Build the wheel (output to `dist/`)
+
+```bash
+# First, build the frontend
+cd frontend
+npm install
+npm run build
+
+# Then, build the backend wheel
+cd ../backend
+uv build --out-dir ../dist
+```
+
+Once built, the wheel is located in the project root `dist/` directory, e.g., `dist/dataclaw-0.1.0-py3-none-any.whl`.
+
+#### Install and Run
+
+```bash
+# We recommend creating a virtual environment first
+python -m venv .venv
+source .venv/bin/activate
+
+# Install DataClaw
+pip install ./dist/dataclaw-*.whl
+
+# Start the service (defaults to http://127.0.0.1:8000)
+dataclaw start
+```
+
+Common service control commands:
+
+```bash
+# Check running status
+dataclaw status
+
+# Custom host/port
+dataclaw start --host 0.0.0.0 --port 8000
+
+# Stop the service
+dataclaw stop
+```
+
+Optional environment variable:
+
+```bash
+export DATA_ROOT=/absolute/path/to/data
+```
+
+If not set, DataClaw uses the repository-level `data/` directory by default. Service state files and logs are located in `DATA_ROOT/run/`.
+
+### 3. Development Mode (Requires Node.js) 🧪
+
+If you want to debug the frontend code or rebuild the frontend artifacts, use the separate development mode:
