+# 教务处通知监控工具
+
+## 功能特点
+
+- 定时监控教务处网站通知
+- 有新通知时自动发送邮件
+- 可配置监控频率（分钟）
+- 状态持久化，记录已发送通知避免重复
+
+## 部署步骤
+
+### 1. 安装依赖
+
+```bash
+pip install -r requirements.txt
+```
+
+### 2. 配置
+
+编辑 `config.yaml`：
+
+```yaml
+monitor:
+  url: "https://jwc.your.edu.cn/tzgg.htm"  # 改为你的教务处地址
+  frequency_minutes: 30  # 监控频率
+  encoding: "utf-8"
+
+notification:
+  smtp_host: "smtp.gmail.com"  # 邮件服务器
+  smtp_port: 587
+  smtp_user: "your_email@gmail.com"
+  smtp_password: "your_app_password"  # 推荐使用应用专用密码
+  to_email: "notify@example.com"
+  use_tls: true
+```
+
+### 3. 运行
+
+```bash
+python main.py
+```
+
+### 4. 后台运行（Linux）
+
+```bash
+nohup python main.py > output.log 2>&1 &
+```
+
+或使用 systemd 服务：
+
+```ini
+[Unit]
+Description=JWC Monitor
+After=network.target
+
+[Service]
+Type=simple
+User=your_user
+WorkingDirectory=/path/to/project
+ExecStart=/usr/bin/python3 main.py
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+### 5. 常见邮件服务商 SMTP 设置
+
+| 服务商 | SMTP Host | 端口 |
+|--------|-----------|------|
+| Gmail | smtp.gmail.com | 587 |
+| QQ | smtp.qq.com | 587 |
+| 163 | smtp.163.com | 465/994 |
+
+**Gmail 提示**：需要开启"应用专用密码"或降低账户安全级别。
+
+## 适配不同网站
+
+如果抓取不到通知，可能需要调整选择器。参考 `main.py` 中的 `_parse_page` 方法，根据实际网页结构修改选择器。
+
+常见问题：
+1. 通知列表在哪个标签里？(ul/div/table)
+2. 每条通知的标题和链接在哪？
+3. 网页编码是什么？
