-Before proceeding, ensure that `Node.js` and `npm` are installed.
-
-```bash
-node --version
-npm --version
-```
-
-If `Node.js` and `npm` are not installed in your environment, refer to the installation guides provided below:
-
-* English version: [https://nodejs.org/en/download](https://nodejs.org/en/download)
-* Chinese version: [https://nodejs.org/zh-cn/download](https://nodejs.org/zh-cn/download)
-
-Select the version that best matches your device specifications and operating system. 
-
-Install the `deepseek-tui` now:
+## Install
+
+`deepseek` ships as a self-contained Rust binary — **no Node.js or Python
+runtime is required to run it.** Pick whichever path you already have on
+your machine; they all land the same binary on your `PATH`.
 
 ```bash
+# 1. npm — easiest if you already use Node. The npm package is a thin
+#    installer that downloads the matching prebuilt binary from GitHub
+#    Releases; it does NOT add a Node runtime dependency to deepseek itself.
 npm install -g deepseek-tui
 
-# When installing deepseek-tui in China's internet environment, you can use an npm mirror to speed up the installation process.
-# npm install -g deepseek-tui@latest --registry=https://registry.npmmirror.com
+# 2. Cargo — no Node needed.
+cargo install deepseek-tui-cli --locked   # `deepseek` (entry point)
+cargo install deepseek-tui     --locked   # `deepseek-tui` (TUI binary)
+
+# 3. Direct download — no Node, no toolchain.
+#    https://github.com/Hmbown/DeepSeek-TUI/releases
+#    Prebuilt for Linux x64/ARM64, macOS x64/ARM64, Windows x64.
 ```
 
+> In mainland China, speed up the npm path with
+> `--registry=https://registry.npmmirror.com`, or use the
+> [Cargo mirror](#china--mirror-friendly-installation) below.

+## 安装
+
+`deepseek` 是单一 Rust 二进制——**运行时不依赖 Node.js 或 Python**。
+下面三种方式装出来的是同一个二进制，按你已有的工具链选一个即可：
+
 ```bash
-npm i -g deepseek-tui
+# 1. npm —— 已装 Node 的最方便方式。npm 包只是一个下载器，
+#    会从 GitHub Releases 拉取对应平台的预编译二进制，
+#    并不会让 deepseek 本身依赖 Node 运行时。
+npm install -g deepseek-tui
+
+# 2. Cargo —— 无需 Node。
+cargo install deepseek-tui-cli --locked   # `deepseek` 入口
+cargo install deepseek-tui     --locked   # `deepseek-tui` TUI 二进制
+
+# 3. 直接下载 —— 无需任何工具链。
+#    https://github.com/Hmbown/DeepSeek-TUI/releases
+#    覆盖 Linux x64/ARM64、macOS x64/ARM64、Windows x64
 ```
 
+> 中国大陆访问较慢时，npm 可加 `--registry=https://registry.npmmirror.com`，
+> 或使用下方的 [Cargo 镜像](#中国大陆--镜像友好安装)。
