+### Compilation de COS2000
+
+#### Logiciels utilisés
+
+L'OS a été développé sous Linux afin de disposer d'un maximum d'outils dont GCC/GAS/Docker et l'ensemble des BINUTILS. Je vous conseille donc d'utiliser Linux afin de procéder à la compilation même si celle-ci peut fonctionner depuis Windows grace à Cygwin. Des distributions "Live" existent si vous ne souhaitez pas installer sur votre ordinateur (http://www.linuxmint.com/edition.php?id=259).
+
+Le système de conteneurisation Docker est exploité afin de d'assurer une reproductibilité totale de l'environnement de compilation quelque soit le système d'exploitation utilisé.
+
+#### Installation/compilation automatique
+
+Téléchargez et exécutez le script d'installation automatique et de compilation "menu.sh"
+
+`wget https://raw.githubusercontent.com/dahut87/cos2000v2/develop/menu.sh`
+
+Executez le script et les sources seront ainsi automatiquement téléchargées sur votre ordinateur par le biais de Git.
+
+`chmod 755 ./menu.sh && ./menu.sh`
+
+Un menu s'affiche ensuite qui vous propose de réaliser différentes tâches dont la compilation et/ou le test de COS2000.
+
+![Menu de compilation](https://github.com/dahut87/cos2000v2/raw/develop/Graphisme/screenshots/compilation.png)
+
+#### Installation/compilation manuelle
+
+##### Téléchargement de COS2000
+
+Afin de faciliter la mise à jour et le suivi des version de COS2000, GIT est utilisé.
+
+Si vous n'avez pas GIT, installez le avec la commande suivante (sous paquet debian .deb):
+
+`sudo apt-get install git`
+
+Puis cloner le source chez vous avec la commande :
+
+`git clone https://github.com/dahut87/cos2000.git`
+
+##### Compilation en ligne de commande
+  
+Docker est utilisé afin de permettre le fonctionnement correcte de la compilation. Au premier lancement de make.sh, si vous utilisez une distribution basée sur le système de paquet Debian, l'installation sera réalisée automatiquement. Dans le cas contraire, installez Docker et relancez le script. Une image docker est produite afin de procéder ensuite à la compilation du système.
+
+Commande de compilation de base
+
+* `./make.sh all` compile tout le projet dans sa version disque dur et disque dur en UEFI
+
+Autres commandes de compilation de COS2000
+
+* `./make.sh harddisk` compile la version disque dur
+* `./make.sh harddiskuefi` compile la version disque dur UEFI
+* `./make.sh test` lance l'émulation QEMU en 32 bits sur disque dur
+* `./make.sh test64` lance l'émulation QEMU en 64 bits sur disque dur en UEFI
+* `./make.sh clean` supprime les fichers compilés
+* `./make.sh syscall` réactualise les librairies du domaine utilisateur
+* `./make.sh programs` compile les programmes du domaine utilisateur
+* `./make.sh config` change la configuration de la compilation
+
+### Utilisation
+
+#### Sur un ordinateur émulé
+
+Pour tester l'OS en émulation taper donc la commande `./make.sh test` qui compilera avant de lancer Qemu.
+
+#### Sur un ordinateur physique
+
+Lancer une compilation du système COS2000
+
+`./make.sh all` 
+
+Puis, il faut copier l'image sur une clé (Attention l'opération effacera le contenu de la clé) :
+
+`sudo dd if=./final/harddisk.img.final of=/dev/sdx bs=1M` (ou sdx est votre périphérique)
+
+Bootez sur votre clé en mode bios (legacy).
+
+Pour un boot en mode UEFI
+
+`sudo dd if=./final/harddiskuefi.img.final of=/dev/sdx bs=1M` (ou sdx est votre périphérique)
+
+Pour connaitre le numéro de votre périphérique (clé)
+
+`lsblk`
+
+#### Commandes de COS2000
+
+Pour l'instant quelques commandes seulement sont disponibles:
+
+* `REBOOT` redémarre le PC,
+* `CLEAR` efface l'écran,
+* `MODE` change le mode video,
+* `DETECTCPU` detecte et affiche les informations CPU,
+* `DETECTPCI` detecte et affiche les périphériques PCI,
+* `TEST2D` teste l'affichage graphique 2D,
+* `TEST3D` teste l'affichage graphique 2D,
+* `REGS` affiche les registres CPU,
+* `GDT` affiche la table des descripteurs,
+* `IDT` affiche la table des interruptions,
+* `MEM` affiche les statistiques d'occupation memoire,
+* `INFO` affiche des informations issues de GRUB,
+* `ERR` génère une exception (ARGUMENTS),
+* `VIEW` visionne la mémoire vive (ARGUMENTS),
+* `LOGO` affiche le logo,
+* `FONT` change la police d'affichage (ARGUMENTS),
+* `HELP` affiche les commandes disponibles,
+* `BPSET` met un point d'arrêt pour le débogueur (ARGUMENTS),
+* `BPCLR` efface un point d'arrêt (ARGUMENTS),
+* `DISASM` désassemble une portion de mémoire (ARGUMENTS),

+ * This file defines four types of data structures: singly-linked lists,
+ * singly-linked tail queues, lists and tail queues.
+ *
+ * A singly-linked list is headed by a single forward pointer. The elements
+ * are singly linked for minimum space and pointer manipulation overhead at
+ * the expense of O(n) removal for arbitrary elements. New elements can be
+ * added to the list after an existing element or at the head of the list.
+ * Elements being removed from the head of the list should use the explicit
+ * macro for this purpose for optimum efficiency. A singly-linked list may
+ * only be traversed in the forward direction.  Singly-linked lists are ideal
+ * for applications with large datasets and few or no removals or for
+ * implementing a LIFO queue.
+ *
+ * A singly-linked tail queue is headed by a pair of pointers, one to the
+ * head of the list and the other to the tail of the list. The elements are
+ * singly linked for minimum space and pointer manipulation overhead at the
+ * expense of O(n) removal for arbitrary elements. New elements can be added
+ * to the list after an existing element, at the head of the list, or at the
+ * end of the list. Elements being removed from the head of the tail queue
+ * should use the explicit macro for this purpose for optimum efficiency.
+ * A singly-linked tail queue may only be traversed in the forward direction.
+ * Singly-linked tail queues are ideal for applications with large datasets
+ * and few or no removals or for implementing a FIFO queue.
+ *
+ * A list is headed by a single forward pointer (or an array of forward
+ * pointers for a hash table header). The elements are doubly linked
+ * so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before
+ * or after an existing element or at the head of the list. A list
+ * may be traversed in either direction.
+ *
+ * A tail queue is headed by a pair of pointers, one to the head of the
+ * list and the other to the tail of the list. The elements are doubly
+ * linked so that an arbitrary element can be removed without a need to
+ * traverse the list. New elements can be added to the list before or
+ * after an existing element, at the head of the list, or at the end of
+ * the list. A tail queue may be traversed in either direction.
+ *
+ * For details on the use of these macros, see the queue(3) manual page.
