 ## 构建依赖
 
+默认只构建桌面客户端。终端主控可通过 `--CROSSDESK_BUILD_DESKTOP=n --CROSSDESK_BUILD_CLI=y` 单独构建；同时开启两个选项可构建两个客户端。CLI 的依赖准备、运行和 npm 打包见 [终端客户端](../apps/cli/README.md)。

 - Git、[Xmake](https://xmake.io/guide/quick-start.html)（桌面端和移动端均要求 3.1.1 或更新版本）及下文对应平台的编译工具链。
 - 构建脚本通过 Xmake 管理 **CMake 3.x（≥ 3.21、< 4.0）**、**Rust 1.92.0** 等依赖；首次构建需要下载工具与源码。具体约束见 [Slint 包配置](../deps/thirdparty/slint/xmake.lua)。

 ## Build requirements
 
+The default configuration builds the desktop client. Use `--CROSSDESK_BUILD_DESKTOP=n --CROSSDESK_BUILD_CLI=y` for the terminal controller alone, or enable both options to build both clients. See the [CLI guide](../apps/cli/README.md) (Chinese) for dependency preparation, usage and npm packaging.

 - Git, [Xmake](https://xmake.io/guide/quick-start.html) (3.1.1 or newer for both desktop and mobile), and the platform toolchain listed below.
 - The build scripts use Xmake to manage **CMake 3.x (≥ 3.21, < 4.0)**, **Rust 1.92.0**, and other dependencies. The first build downloads tools and source archives. See the [Slint package configuration](../deps/thirdparty/slint/xmake.lua) for the constraints.
