+### 可选依赖
+
+TUI 依赖 [gum](https://github.com/charmbracelet/gum)（Charm 出品的终端 UI 工具）。gum 不是主安装依赖；未安装时仅 `clashctl tui` 不可用，`clashon`、`clashoff`、`clashctl select`、`status`、`doctor` 等命令不受影响。
+
+安装项目时会询问是否安装 gum，默认跳过；也可以安装后单独执行：
+
+```bash
+clashctl tui install-gum
+```
+
+非交互安装时可通过环境变量控制：
+
+```bash
+CLASH_INSTALL_GUM=true bash install.sh
+CLASH_INSTALL_GUM=false bash install.sh
+```
+
+```bash
+# macOS
+brew install gum
+
+# Arch Linux
+pacman -S gum
+
+# Ubuntu/Debian
+sudo mkdir -p /etc/apt/keyrings
+curl -fsSL https://repo.charm.sh/apt/gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/charm.gpg
+echo "deb [signed-by=/etc/apt/keyrings/charm.gpg] https://repo.charm.sh/apt/ * *" | sudo tee /etc/apt/sources.list.d/charm.list
+sudo apt update && sudo apt install gum
+
+# Fedora/RHEL
+echo '[charm]
+name=Charm
+baseurl=https://repo.charm.sh/yum/
+enabled=1
+gpgcheck=1
+gpgkey=https://repo.charm.sh/yum/gpg.key' | sudo tee /etc/yum.repos.d/charm.repo
+sudo rpm --import https://repo.charm.sh/yum/gpg.key
+sudo yum install gum
+
+# Go
+go install github.com/charmbracelet/gum@latest
+```
+
+> 如果未安装 gum，其他所有命令行功能仍然完全可用，仅 `clashctl tui` 不可用。
+
 # 🚀 一键安装（推荐）
 
 在终端中执行以下命令即可完成安装：
