+CustomCertificate plugin
+===============
+Este plugin da la posibilidad al administrador de disponer de una herramienta de certificados alternativa
+ a la que tiene por defecto la plataforma Chamilo.
+
+**Instrucciones de puesta en funcionamiento**
+
+- Habilitar el plugin en la administración de Chamilo.
+- Indicar 'menu_administrator' en la configuración de la región del plugin.
+
+**accesos a la herramienta**
+
+- Desde la pantalla de Administración para configurar el certificado por defecto.
+- Desde las herramientas del curso, para la configuración del diploma especifico.
+
+**Importante a tener en cuenta**
+
+Por defecto los certificados utilizados serán los de la plataforma chamilo. Para habilitar el certificado alternativo
+en un curso se debe entrar en la configuración del curso y habilitar en la pestaña de "certificados personalizado" la 
+casilla de verificación de "Habilitar en el curso el certificado alternativo".
+Si se desea usar el certificado por defecto se deberá mostrar la segunda casilla de verificación.
