+> Implementar los botones solo necesitas hacer uso del metodo __sendMessageButton__ que se encuentra dentro `./controllers/send` dejo un ejemplo de como usarlo.
+[Ver implementación](https://github.com/leifermendez/bot-whatsapp/blob/main/app.js#L123)
+
+``` javascript
+const { sendMessageButton } = require('./controllers/send')
+
+await sendMessageButton(
+    {
+        "title":"¿Que te interesa ver?",
+        "message":"Recuerda todo este contenido es gratis y estaria genial que me siguas!",
+        "footer":"Gracias",
