 ##Comment utilisé le Noyaux Générer ?
 
-> Un fichier PiegOS est créer à la racine du projet si la compilation c'est bien déroulée. Il n'y a plus qu'à le copier sur un support ou
-à le lancer dans une machine virtuelle.
+> Un fichier PiegOS est créer à la racine du projet aprés l'éxécution de make. Il n'y a plus qu'à charger ce fichier à l'aide d'un chargeur d'amorçage (Grub, LILO etc..).
+
+##Notes
+
+> Le bootloader n'est présent qu'à titre informatif. Pour le lancer, il suffit de le placer au premier secteur du support de boot.
