+# Weidian Snatch (微店抢购脚本)
+
+这是一个基于 [Playwright](https://playwright.dev/) 的微店自动抢购工具，支持精确计时、自动登录、隐身模式等功能。
+
+## 功能特性
+
+- **自动登录**：支持保存和加载登录状态 (`auth_state.json`)。
+- **精确计时**：内置 `PrecisionTimer` 进行时间同步和倒计时等待。
+- **隐身模式**：使用 stealth 脚本隐藏自动化特征，降低防爬虫检测风险。
+- **自动抢购**：自动执行点击购买、确认规格（SKU）、提交订单的流程。
+
+## 文件结构
+
+- `main.py`: 主程序入口，包含抢购的核心逻辑。
+- `config.yaml`: 配置文件，设置商品链接、抢购时间、浏览器模式等。
+- `resolve_url.py`: URL 解析工具（如果有）。
+- `utils/`:
+  - `auth.py`: 处理用户认证和 Session 管理。
+  - `stealth.py`: 反爬虫隐身处理。
+  - `timer.py`: 时间同步与控制。
+
+## 使用方法
+
+1. **安装依赖**
+   请确保已安装 Python，并安装所需的库：
+   ```bash
+   pip install playwright pyyaml
+   playwright install
+   ```
+
+2. **配置 config.yaml**
+   修改 `config.yaml` 文件，填入目标商品 URL (`target_url`) 和抢购时间 (`snatch_time`)。
+
+3. **运行脚本**
+   ```bash
+   python main.py
+   ```
+   如果是首次运行且无登录状态，脚本会提示登录。请手动登录后，脚本会自动保存状态供下次使用。
+
+## 注意事项
+
+- 请确保网络畅通，以保证时间同步和抢购请求的及时发送。
+- 抢购成功率受多种因素影响（网络延迟、库存数量、平台风控等），本脚本仅辅助操作，不保证 100% 成功。
