+# Open Design Windows Launcher
+
+`OpenDesignLauncher.cs` builds a small Windows console executable that starts the
+local development app without typing the normal commands by hand.
+
+The compiled `OpenDesign.exe` is intentionally not committed to git. Build it
+locally when you want the shortcut, or download a trusted build from GitHub
+Releases if the project publishes one.
+
+## Build
+
+From the repository root on Windows:
+
+```powershell
+C:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe /target:exe /out:OpenDesign.exe /win32icon:tools\pack\resources\win\icon.ico tools\launcher\OpenDesignLauncher.cs
+```
+
+If your Windows installation only has the 32-bit .NET Framework compiler, use:
+
+```powershell
+C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe /target:exe /out:OpenDesign.exe /win32icon:tools\pack\resources\win\icon.ico tools\launcher\OpenDesignLauncher.cs
+```
+
+## Run
+
+Place the built `OpenDesign.exe` in the repository root next to `package.json`,
+then double-click it.
+
+The launcher checks for dependencies and runs:
+
+```powershell
+corepack pnpm install
+corepack pnpm tools-dev
+```
