 # Soul:23 coming soon page
 
-A responsive landing page built with Bootstrap 4 that keeps a countdown and lets visitors request updates via the email form. A live preview is available at https://solu23.cloud.
+Una landing page responsive Built con Bootstrap 4 que muestra una cuenta regresiva y un formulario de notificaciones. Se accede a una versión viva en https://solu23.cloud.
 
 **Author:** Marco Gallegos
 
-## Subscription form
+## Instalación local
 
-The notification form is purely client-side; fill it out, but no emails are sent or stored until you connect it to your own backend.
+```bash
+npm install
+npm start
+```
 
-## Changing the countdown target
+El servidor Express sirve todos los assets desde la raíz y expone `/healthchecker` con el script de salud como `text/plain`, listo para que operadores lo descarguen con `curl`.
 
-The timer reads its target date from the `data-date` attribute on the `#countdown-timer` element in `index.html`. Update that attribute to any valid timestamp, for example:
+## Deploy con Coolify / Traefik
+
+1. Importa el repositorio como app Docker en Coolify.
+2. Elige el `Dockerfile` del proyecto, expone el puerto `3000` (ya definido en el contenedor).
+3. Coolify/Traefik se encargan del TLS; usa el dominio que asignas en la app.
+4. Si necesitas alertas, define la variable de entorno `WEBHOOK_URLS` antes de levantar la app.
+
+Una vez desplegado podrás invocar el verificador con:
+
+```bash
+curl https://tudominio.cloud/healthchecker
+```
+
+## Contador y formulario
+
+El componente de tiempo lee el atributo `data-date` en `#countdown-timer`. Cámbialo por cualquier fecha válida:
 
 ```html
 <div id="countdown-timer" data-date="January 17, 2025 03:24:00">
 ```
 
-If you prefer keeping the attribute dynamic, reassign the `countDownDate` variable inside `js/countdown.js` before the interval starts.
+Si prefieres programarlo con JavaScript, reasigna la variable `countDownDate` dentro de `js/countdown.js` antes de que empiece el intervalo.
