-                <tr><th>项目</th><th>说明</th></tr>
-                <tr><td>操作系统</td><td>Linux（需 systemd），也支持 Windows</td></tr>

-            <h3>2. 获取源码</h3>
-            <p style="margin-bottom:6px;">方式一：Git 克隆（推荐，仅拉取必要文件，排除仓库冗余）</p>
-            <pre>git clone --depth 1 --single-branch \
-  https://gitee.com/SCU_team/mine-sentinel.git \
-  /opt/minecraft/sentinel
-# --depth 1      仅拉取最新提交，不下载历史记录
-# --single-branch 仅拉取 master 分支</pre>
-            <p style="margin-bottom:6px;">方式二：手动复制</p>
-            <pre>mkdir -p /opt/minecraft/sentinel
-cp main.rb method_executor.rb server_status_detector.rb \
-   /opt/minecraft/sentinel/</pre>
-
-            <h3>3. 手动测试</h3>
-            <pre>cd /opt/minecraft/sentinel
-ruby main.rb
-# 调试模式: LOG_LEVEL=debug ruby main.rb</pre>
-
-            <h3>4. 注册 systemd 服务</h3>
-            <p>项目源码中已提供 <code>minesentinel.service</code>，直接复制：</p>
-            <pre>cp minesentinel.service /etc/systemd/system/</pre>

-            <pre>journalctl -u minesentinel -f          # 实时
-journalctl -u minesentinel -u minecraft -f  # 双服务合并</pre>

-            <ul>
-                <li><strong>Docker：</strong>替换重启命令为 <code>spawn "docker restart mc-server"</code></li>
-                <li><strong>screen：</strong><code>system "screen -S mc -X quit"; system "screen -dmS mc java ..."</code></li>
-                <li><strong>Windows：</strong>删除 root 检查，替换为 <code>spawn "cmd /c start /B java ..."</code>，日志输出到文件</li>
-                <li><strong>监控其他服务：</strong>修改 <code>test_port</code> 的 IP 和端口即可</li>
