+====== Installation de la raspberry Pi ======
+===== Utilisation du version minimaliste de raspbian =====
+Nous avons choisis une version minimaliste de raspbian disponnible ici :
+http://www.linuxsystems.it/raspbian-wheezy-armhf-raspberry-pi-minimal-image/
+Pour préparer la carte SD suivre le tuto ici (section command line interface) :
