+## 一起看 (VideoTogether) 配置
+
+播放器页面和 IPTV 页面默认内置 [VideoTogether](https://videotogether.github.io/zh-cn/guide/website.html) 官方网页集成脚本，进入播放页后即可直接使用一起看功能。
+
+| 变量名 | 说明 | 默认值 |
+|--------|------|--------|
+| `VIDEOTOGETHER_ENABLED` | 设为 `false` 时禁用一起看集成 | `true` |
+| `VIDEOTOGETHER_SCRIPT_URL` | 自定义 VideoTogether 脚本地址，适合自托管或替换 CDN | `https://fastly.jsdelivr.net/gh/VideoTogether/VideoTogether@latest/release/extension.website.user.js` |
+| `VIDEOTOGETHER_SETTING_URL` | 自定义 VideoTogether 设置页地址，对应官方 `window.videoTogetherWebsiteSettingUrl` 接口 | - |
+
+**示例：**
+
+```bash
+# Docker
+docker run -d -p 3000:3000 \
+  -e VIDEOTOGETHER_SCRIPT_URL="https://your-domain.example.com/extension.website.user.js" \
+  -e VIDEOTOGETHER_SETTING_URL="https://your-domain.example.com/videotogether-settings.html" \
+  --name kvideo kuekhaoyang/kvideo:latest
+```
+
+> 如果部署环境无法稳定访问 jsDelivr，直接自托管 `extension.website.user.js` 并通过 `VIDEOTOGETHER_SCRIPT_URL` 指向自己的地址即可。

 ## IPTV 直播源配置
 
 通过环境变量预设 IPTV 直播源，应用启动时会自动添加到直播源列表中。
