+# Electron wrapper (Windows)
+
+Este wrapper crea una app de escritorio para Windows que lanza NodeCG sin requerir que el usuario final tenga Node.js instalado.
+
+## Requisitos de build (solo para quien genera el instalador)
+
+1. Instalar dependencias del bundle raíz:
+
+   ```bash
+   pnpm install
+   ```
+
+2. Instalar dependencias del wrapper:
+
+   ```bash
+   cd electron
+   pnpm install
+   ```
+
+## Desarrollo local
+
+Desde `electron/`:
+
+```bash
+pnpm start
+```
+
+## Generar instalador `.exe` (comprimido)
+
+Desde `electron/`:
+
+```bash
+pnpm dist:win
+```
+
+Esto genera un instalador NSIS en `electron/dist/` con compresión máxima (`compression: maximum`).
+
+## Qué incluye el instalador
+
+- Runtime de Electron (incluye Node embebido).
+- Dependencia `nodecg` dentro de la app.
+- El bundle `scoreko-dev` como recurso (`resources/bundle`).
+
+Con eso, el usuario final instala y ejecuta la app sin instalar Node.js aparte.
+
+## Variables opcionales
+
+- `NODECG_PORT` (por defecto `9090`)
+- `NODECG_HOST` (por defecto `127.0.0.1`)
