+
+[English](README.md) | 简体中文
+
+## 安装
+
+**Unix（Linux/macOS）：**
+
+```bash
+curl -fsSL https://eightarms.net/Octopus/octopus-release/raw/branch/main/install | bash
+```
+
+**Windows（PowerShell）：**
+
+```powershell
+[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
+irm https://eightarms.net/Octopus/octopus-release/raw/branch/main/install.ps1 | iex
+```
+
+### 手动安装
+
+若一键脚本报连接错误，说明你的网络可能过滤了到 `eightarms.net` 的直连。请从
+[releases 页面](https://eightarms.net/Octopus/octopus-release/releases/latest) 下载对应平台的压缩包手动安装。
+
+**Unix（Linux/macOS）：**
+
+```bash
+# 从 releases 页面下载 octopus-<platform>.tar.gz 后
+tar -xzf octopus-linux-x64.tar.gz
+sudo mv octopus /usr/local/bin/
+octopus --version
+```
+
+**Windows（PowerShell）：** 下载 `octopus-windows-x64.zip` 后：
+
+```powershell
+$zip = "$env:USERPROFILE\Downloads\octopus-windows-x64.zip"
+$dest = "$env:USERPROFILE\.octopus\bin"
+$tmp  = Join-Path $env:TEMP "octopus_manual"
+New-Item -ItemType Directory -Force -Path $dest,$tmp | Out-Null
+Expand-Archive -Path $zip -DestinationPath $tmp -Force
+Copy-Item "$tmp\octopus.exe" "$dest\octopus.exe" -Force
+Remove-Item -Recurse -Force $tmp
+$p = [Environment]::GetEnvironmentVariable('Path','User')
+if ($p -notlike "*$dest*") { [Environment]::SetEnvironmentVariable('Path', ($p.TrimEnd(';') + ";$dest"), 'User') }
+& "$dest\octopus.exe" --version
+```
+
+然后打开一个**新**终端运行 `octopus`。
+
+## 桌面版（beta）
+
+偏好图形界面？Octopus 桌面应用与 CLI 一同发布 Windows / Linux beta 构建：
+
+- **Windows：** 从 [`desktop-beta` 频道](https://eightarms.net/Octopus/octopus-release/releases/tag/desktop-beta) 下载
+  [`octopus-desktop-win-x64.exe`](https://eightarms.net/Octopus/octopus-release/releases/download/desktop-beta/octopus-desktop-win-x64.exe)
+  安装；已安装的构建会从同一频道自动更新。
+- **Linux (x86_64)：** 从同一 [`desktop-beta` 频道](https://eightarms.net/Octopus/octopus-release/releases/tag/desktop-beta) 下载
+  [`octopus-desktop-linux-x86_64.AppImage`](https://eightarms.net/Octopus/octopus-release/releases/download/desktop-beta/octopus-desktop-linux-x86_64.AppImage)，赋权后运行：
+
+  ```bash
+  chmod +x octopus-desktop-linux-x86_64.AppImage
+  ./octopus-desktop-linux-x86_64.AppImage
+  ```
+
+  AppImage 自动更新（`latest-linux.yml`）。需要原生包？同频道另有
+  [`octopus-desktop-linux-amd64.deb`](https://eightarms.net/Octopus/octopus-release/releases/download/desktop-beta/octopus-desktop-linux-amd64.deb) /
+  [`octopus-desktop-linux-x86_64.rpm`](https://eightarms.net/Octopus/octopus-release/releases/download/desktop-beta/octopus-desktop-linux-x86_64.rpm)（仅限首装、不自动更新，且未签名会触发首次安装警告）。
+
+- 这是 beta 频道，会有粗糙之处；macOS 构建在计划中但尚未发布。
