+La volontà di scrivere questo manuale nasce nel 2018 in occasione di un corso di formazione medio base volto ai richiedenti asilo del progetto SPRAR, come riferimento di fondo per coordinare le lezioni.\\
+È stato raccolto online del materiale ed è stato di grande aiuto il progetto già avviato dal gruppo ``Officina S3", da cui si è tratto parecchio spunto.\\
+Speriamo di poter utilizzare il testo per i futuri soci dell'Officina Informatica o per organizzare corsi base di informatica incentrati sul Sistema Operativo libero e sugli applicativi correlati.
