+# Grbl
+
+**parallel-port-based motion control for CNC milling** 
+
+[About](https://github.com/grbl/grbl/wiki#about-grbl) Grbl  
+
+Grbl is a free, open source, high performance software for controlling the motion  
+of machines that move, that make things, or that make things move, and will run  
+on a straight Arduino.  
+If the maker movement was an industry, Grbl would be the industry standard.  
+
+Most open source 3D printers have Grbl in their hearts.  
+It has been adapted for use in hundreds of projects including laser cutters,  
+automatic hand writers, hole drillers, graffiti painters and oddball drawing machines.  
+Due to its performance, simplicity and frugal hardware requirements Grbl has grown  
+into a little open source phenomenon.
+
+----
+
+Este sketch compila y sube **Grbl** a un **Arduino 328p**
+
+Pasos:
+
+- Primero, asegurate de importar el código base de Grbl en el IDE ([ayuda](https://github.com/gnea/grbl/wiki/Flashing-Grbl-to-an-Arduino))  
+
+- Selecciona el Arduino el puerto Serial en el menu de herramientas.
+  **NOTE:** oficialmente Grbl solo soporta **Arduinos 328p**, como **Arduino Uno**.
+  Usar otras tarjetas puede no funcionar!
+
+- Haz click en Subir/Upload el sketch
+
+`./grblUpload.ino`
+```c
+#include <grbl.h>
