 ### Option A: One-line install (recommended, macOS / Linux)

+To open PilotDeck again later on macOS / Linux, run `pilotdeck` in a terminal and open the printed URL in your browser. If your shell has not picked up the PATH update yet, open a new terminal or source your shell profile first.
+
+```bash
+pilotdeck
+# then open http://localhost:3001, or the URL printed by the command
+```
+
+### Option A2: One-line install (Windows PowerShell)
+
+Run PowerShell as a normal user, then execute:
+
+```powershell
+powershell -ExecutionPolicy Bypass -c "irm https://raw.githubusercontent.com/OpenBMB/PilotDeck/main/install.ps1 | iex"
+```
+
+The PowerShell installer uses Windows-native paths under `%USERPROFILE%\.pilotdeck`, checks Node.js 22.13+ with `node:sqlite`, installs missing prerequisites with `winget` when available, builds PilotDeck, and creates a `pilotdeck.cmd` launcher in `%USERPROFILE%\.pilotdeck\bin`. Git LFS media assets are optional for the core app; if Git LFS is unavailable or times out, the installer continues without demo videos/GIFs.
+
+After installation, the script starts PilotDeck and prints the UI URL, usually `http://localhost:3001`. It does not automatically open a browser, so copy that URL into your browser to finish onboarding (provider + API key). You can also open it from PowerShell:
+
+```powershell
+Start-Process http://localhost:3001
+```
+
+If this is your first install, open a new PowerShell window after the script updates your user `PATH`, then run:
+
+```powershell
+pilotdeck            # starts the server at http://localhost:3001
+pilotdeck status     # check runtime status
+```
+
+To open PilotDeck again later, run `pilotdeck` from a new PowerShell window, then open the printed URL in your browser. If `pilotdeck` is not yet on `PATH`, run the launcher directly:
+
+```powershell
+& "$HOME\.pilotdeck\bin\pilotdeck.cmd"
+```
+
+#### Windows PowerShell FAQ
+
+**`npm.ps1` cannot be loaded because running scripts is disabled**
+
+This can still happen when you run development commands such as `npm run dev` directly in Windows PowerShell for the first time. PowerShell may resolve `npm` to `npm.ps1`, and the default execution policy can block that shim.
+
+Fix it once for the current user, then reopen PowerShell:
+
+```powershell
+Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
+```
+
+If you do not want to change the user policy, run the cmd shim explicitly instead:
+
+```powershell
+npm.cmd run dev
+```
+
+**Native dependency build errors (`node-gyp`, `MSBuild`, or Python not found)**
+
+The installer normally uses prebuilt packages for native dependencies such as `node-pty`, `sqlite3`, `better-sqlite3`, and `sharp`. On a fresh Windows machine, if npm cannot download a matching prebuild and falls back to compiling from source, install Visual Studio Build Tools with the C++ workload and Python, then rerun the installer.

 ### Option B: From source (for developers)
 
 **1. Clone and install dependencies**

+之后如果想在 macOS / Linux 上再次打开 PilotDeck，请在终端运行 `pilotdeck`，然后在浏览器中打开终端打印的地址。如果当前 shell 还没有刷新 PATH，请新开一个终端，或先 source 对应的 shell 配置文件。
+
+```bash
+pilotdeck
+# 然后打开 http://localhost:3001，或命令打印的地址
+```
+
+### 方式一补充：一键安装 (Windows PowerShell)
+
+在普通用户 PowerShell 中执行：
+
+```powershell
+powershell -ExecutionPolicy Bypass -c "irm https://raw.githubusercontent.com/OpenBMB/PilotDeck/main/install.ps1 | iex"
+```
+
+PowerShell 安装脚本会使用 `%USERPROFILE%\.pilotdeck` 下的 Windows 原生路径，检查 Node.js 22.13+ 与 `node:sqlite`，在可用时通过 `winget` 安装缺失依赖，构建 PilotDeck，并在 `%USERPROFILE%\.pilotdeck\bin` 生成 `pilotdeck.cmd` 启动器。Git LFS 媒体资源对核心功能是可选的；如果 Git LFS 不可用或下载超时，安装脚本会跳过演示视频/GIF 并继续安装。
+
+安装完成后，脚本会启动 PilotDeck 并打印 UI 地址，通常是 `http://localhost:3001`。脚本不会自动打开浏览器，请把该地址复制到浏览器中完成初始化配置（Provider + API key）。也可以在 PowerShell 中打开：
+
+```powershell
+Start-Process http://localhost:3001
+```
+
+如果脚本刚刚更新了用户 `PATH`，请新开一个 PowerShell 窗口后运行：
+
+```powershell
+pilotdeck            # 在 http://localhost:3001 启动服务
+pilotdeck status     # 查看运行状态
+```
+
+之后如果想再次打开 PilotDeck，请在新的 PowerShell 窗口运行 `pilotdeck`，然后在浏览器中打开终端打印的地址。如果当前窗口还识别不到 `pilotdeck`，可以直接运行启动器：
+
+```powershell
+& "$HOME\.pilotdeck\bin\pilotdeck.cmd"
+```
+
+#### Windows PowerShell FAQ
+
+**首次运行 `npm run dev` 报错：`npm.ps1` 因系统禁止运行脚本而无法加载**
+
+这个问题现在仍可能出现：当你在 Windows PowerShell 中直接运行 `npm run dev` 等开发命令时，PowerShell 可能优先解析到 `npm.ps1`，而默认执行策略会阻止该脚本。
+
+对当前用户设置一次执行策略，然后重新打开 PowerShell：
+
+```powershell
+Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned
+```
+
+如果不想修改用户执行策略，也可以显式调用 cmd shim：
+
+```powershell
+npm.cmd run dev
+```
+
+**原生依赖构建失败（提示 `node-gyp`、`MSBuild` 或 Python 缺失）**
+
+安装脚本通常会使用 `node-pty`、`sqlite3`、`better-sqlite3`、`sharp` 等原生依赖的预编译包。全新的 Windows 机器上，如果 npm 无法下载匹配的预编译包并回退到源码编译，请先安装带 C++ 工作负载的 Visual Studio Build Tools 和 Python，然后重新运行安装脚本。
