Funciona como una especie de de administrador de proyectos que ayuda al programador a administrar las dependencias que se utilizarán proyecto por proyecto.
Este artículo asume que tiene al menos conocimientos básicos de Linux, sabe cómo usar el shell y, lo que es más importante, aloja su sitio en su propio VPS.
