+# DID WBA Server with uv
+
+This project uses [uv](https://docs.astral.sh/uv/) as the Python package manager.
+
+## Prerequisites
+
+- Install [uv](https://docs.astral.sh/uv/)
+- Python 3.9 or later
+
+## Setup
+
+1. Install Python (if not already installed):
+   ```bash
+   uv python install 3.9
+   ```
+
+2. Create and activate a virtual environment:
+   ```bash
+   uv venv
+   source .venv/bin/activate  # On Windows: .venv\Scripts\activate
+   ```
+
+3. Install dependencies:
+   ```bash
+   uv pip install -e .
+   ```
+
+## Running the Application
+
+```bash
+uvicorn did_server:app --reload
+```
+
+## Development
+
+- To add a new dependency:
+  ```bash
+  # 1. 安装新包
+  uv pip install package_name
+  
+  # 2. 更新 pyproject.toml 中的 dependencies 列表
+  
+  # 3. 重新安装项目依赖
+  uv pip install -e .
+  ```
+
+- To update all dependencies:
+  ```bash
+  # 更新所有包到最新版本
+  uv pip install --upgrade -e .
+  ```
+
+## Cleaning Up
+
+To remove the virtual environment:
+
+```bash
+rm -rf .venv
+```

-### Install Dependencies with Poetry
+### Install Dependencies with uv
+
+[uv](https://github.com/astral-sh/uv) is an extremely fast Python package manager and resolver written in Rust.
 
 ```bash
-# Create virtual environment and install dependencies with Poetry
-poetry install
+# Install uv (if not already installed)
+curl -sSf https://astral.sh/uv/install.sh | sh
 
-# Activate virtual environment
-poetry shell
+# Create and activate virtual environment
+uv venv
+source .venv/bin/activate  # On Windows: .venv\Scripts\activate
 
-# Or activate virtual environment this way (if it already exists)
-source .venv/bin/activate
+# Install project dependencies
+uv pip install -e .
 ```
 
+For more uv usage instructions, please refer to the [UV Guide](README-uv.md)

-### 使用Poetry安装依赖
+### 使用 uv 安装依赖
+
+[uv](https://github.com/astral-sh/uv) 是一个快速的 Python 包管理器和解析器，使用 Rust 编写。
 
 ```bash
-# 使用Poetry创建虚拟环境并安装依赖
-poetry install
+# 安装 uv (如果尚未安装)
+curl -sSf https://astral.sh/uv/install.sh | sh
 
-# 激活虚拟环境
-poetry shell
+# 创建并激活虚拟环境
+uv venv
+source .venv/bin/activate  # Windows: .venv\Scripts\activate
 
-# 或者使用以下方式激活虚拟环境(如果已存在)
-source .venv/bin/activate
+# 安装项目依赖
+uv pip install -e .
 ```
 
+更多 uv 使用说明请参考 [UV 使用指南](README-uv.md)
