-### 方式四：Linux 一键安装
+### 方式四：Linux 安装脚本
+
+Linux 下有两个脚本，按需二选一：
+
+| | `scripts/install.sh`（一键安装 + 系统服务） | `scripts/setup.sh`（只安装构建） |
+|---|---|---|
+| 适合 | 想开箱即用、开机自启的服务器 | 想自己决定怎么常驻（screen / tmux / pm2 / 自写服务）的用户，或 macOS |
+| Node.js | 没有或版本过低时**自动安装 Node 22 LTS**（apt / yum / pacman） | **不会安装**，需先自行装好 Node 22.12+ |
+| 系统依赖 | 自动安装构建工具（和 FFmpeg，作为内置 FFmpeg 的后备） | 不安装，只提示 |
+| 安装位置 | 构建后复制到 `/opt/tsmusicbot`（重装时保留 `data/`） | 就在当前项目目录 |
+| 系统服务 | 自动配置 systemd 服务 `tsmusicbot` 并开机自启 | **不配置服务**，完成后自己 `npm start` |
+| 需要 root | 是（`sudo`） | 否 |
+
+两者共用同一套安装逻辑：`install.sh` 会调用 `setup.sh` 完成依赖安装、国内网络镜像切换、原生模块校验和构建，然后再复制文件、配置服务。
+
+**一键安装 + systemd 服务：**
 
 ```bash
 chmod +x scripts/install.sh
 sudo ./scripts/install.sh
+# 之后：systemctl status|restart|stop tsmusicbot，日志：journalctl -u tsmusicbot -f
 ```
 
-自动安装 Node.js 和依赖，配置 systemd 服务，支持开机自启。
+**只安装构建（不装 Node、不配服务）：**
+
+```bash
+bash scripts/setup.sh
+npm start
+```

 > 完整历史请查看 [git log](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/commits/main) 或 [Releases](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/releases)。这里只列出重要变更和面向用户的破坏性改动。
 
-### 最新版本 — v1.13.0：本地视频上传播放 / 头像上传时机
+### 最新版本 — v1.14.0：歌单链接直接播放 / 每人绑定自己的网易云私人FM / B站分P
+
+处理了 5 个社区反馈的 issue。**没有配置变化，升级无需任何操作**；数据库会自动新增一张表（存放用户自己绑定的网易云账号），原有数据不受影响。
+
+**`!playlist` 直接粘贴歌单链接（[#160](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/160)，[PR #169](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/pull/169)，感谢 [@JiaxiangACE](https://github.com/JiaxiangACE)）**
+
+- `!playlist <歌单链接>` 支持网易云 / QQ 音乐 / YouTube 歌单链接，**平台由链接自动识别**：以前 QQ 链接不加 `-q` 会被拿去网易云查，YouTube 的 `?list=` 链接会被当成歌单名去搜索，现在都能直接用。
+- App 里「分享」复制出来的整段文案、以及短链（`163cn.tv`、`c6.y.qq.com`）也能直接粘贴。短链只会访问这两个域名，不会去请求任意用户给的地址。
+- 歌单名和纯数字 ID 的用法不变。
+
+**每个网页端用户绑定自己的网易云账号听私人FM（[#164](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/164)，[PR #171](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/pull/171)，感谢 [@xxmod](https://github.com/xxmod)）**
+
+- 多人共用一个机器人时，私人FM以前永远按机器人登录的那一个账号推荐。现在每个成员可以在 **设置 → 账户** 扫码绑定自己的网易云账号，之后他在网页端开启的网易云私人FM按他自己的口味推荐；未绑定的人照旧使用共享账号。
+- 绑定的登录只保存在服务器上，从不回传给浏览器，也**不会**顶掉机器人的共享登录；删除用户时一并清除。游客不能绑定。
+- TS 聊天里的 `!fm` 仍使用共享账号（聊天里的 TS 用户和网页账号没有对应关系）。
+
+**机器人被移动后，原频道描述不再残留（[#159](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/159)，[PR #168](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/pull/168)，感谢 [@Almighty-ap](https://github.com/Almighty-ap)）**
+
+- 开启「更新频道描述」时，把机器人拖到别的频道后，原频道会一直停留在当时的歌曲信息。现在机器人被移动时会清空原频道描述，并把正在播放的信息写到新频道。
+
+**Linux 安装脚本（[#165](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/issues/165)，[PR #172](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/pull/172)，感谢 [@XuVIIJay](https://github.com/XuVIIJay)）**
+
+- `scripts/install.sh` 以前仍在安装已不再支持的 Node 20，现在按发行版（apt / yum / pacman）安装 Node 22 LTS，并复用 `setup.sh` 完成依赖安装、国内镜像切换、原生模块校验和构建。重复运行（升级）时会先停服务、替换构建产物，**保留 `data/`**。
+- README 的「Linux 安装脚本」一节说明了 `install.sh`（一键安装 + systemd 开机自启）和 `setup.sh`（只安装构建、不装 Node、不配服务）的区别和适用场景。
+
+**B站分P视频（[PR #166](https://github.com/ZHANGTIANYAO1/teamspeak-music-bot/pull/166)，感谢 [@xxmod](https://github.com/xxmod)）**
+
+- 分P视频以前只能播放第一P，且时长显示为整个视频的总时长。现在网页端播放多P视频时会弹出选择框选P；TS 里 `!play` 播放第一P。
+
+### v1.13.0：本地视频上传播放 / 头像上传时机
 
 处理了 2 个社区反馈的 issue。**没有配置变化，升级无需任何操作**；原有的本地音频上传行为完全不变。
