 ### Requirements
 
-- [Go](https://go.dev/dl/) 1.21+
+#### macOS
-- [Wails CLI](https://wails.io/docs/gettingstarted/installation): `go install github.com/wailsapp/wails/v2/cmd/wails@latest`
+
-- [Node.js](https://nodejs.org/) 18+ (for frontend build)
+1. Install [Homebrew](https://brew.sh/) (if not already installed)
-- macOS: Xcode Command Line Tools (`xcode-select --install`)
+2. Install dependencies:
+   ```bash
+   brew install go node
+   xcode-select --install          # Xcode Command Line Tools
+   go install github.com/wailsapp/wails/v2/cmd/wails@latest
+   ```
+
+#### Windows
+
+1. Install dependencies (using [winget](https://learn.microsoft.com/en-us/windows/package-manager/winget/), built into Windows 10/11):
+   ```powershell
+   winget install GoLang.Go
+   winget install OpenJS.NodeJS.LTS
+   go install github.com/wailsapp/wails/v2/cmd/wails@latest
+   ```
+   Or download manually: [Go](https://go.dev/dl/) 1.21+, [Node.js](https://nodejs.org/) 18+
+2. **WebView2 Runtime** — required by Wails. Pre-installed on most Windows 10/11 machines with Edge. If missing, download from [Microsoft](https://developer.microsoft.com/en-us/microsoft-edge/webview2/).
+
+#### Version Summary
+
+| Tool | Minimum | Install docs |
+|------|---------|--------------|
+| Go | 1.21+ | https://go.dev/dl/ |
+| Node.js | 18+ | https://nodejs.org/ |
+| Wails CLI | v2 | https://wails.io/docs/gettingstarted/installation |
 
 ### Build
