#README.md#

+Instrucciones para poder utilizar la agenda es entrando en la carpeta poker(no ingrese en la carpeta agenda porque era de prueba) y al crear un registro utilice la flecha para volver ya que en el momento de crear el archivo cerrar el programa, el primer archivo se elimina. Luego el resto su uso es normal.
