 Debian Auto Installer
-=====================
+====================
 
-A script to create automated Debian Installation Key. I created it for my work.
- You can create bios, efi64 key or prepare files into a folder whitout creating 
-key. 
+A set of tools to create automated Debian Installation Key. I created this tools
+for my work. You can create bios, efi64 key but prepare file in the folder
+ whitout creating key.
  
  * init.sh : script to create USB key
- * preseeds : folder containing all preseeds files
- * partman_recipes : folder containinf partman recipes
+ * preseed : textfile that contain all instructions for Debian Installer
+ * partman : partition recipe for preseed
  * syslinux/syslinux.cfg : Syslinux configuration file
- * conf/*.conf : "folder configuration" files
 
+# Howto create usb key
+
+ 1. Plug your key
+ 2. Make sure yout key is not mounted
+ 3. Execute ``./init.sh -d /dev/sdb`` (replace /dev/sdb with your device)
+ 4. Done!
 
 # Init.sh command line options
 
  * ``-a [amd64|i386]`` choose architecture for debian files (default amd64)
  * ``-b`` create key for bios boot architecture (default efi64)
- * ``-c --conf`` set folder configuration files (default conf/archlinux.conf)
  * ``-d device`` USB device like /dev/sdb
- * ``--debian-version`` debian iso version to download (default lastest stable)
- * ``--repo`` repository folder (default ./repo)
- * ``--tmp`` Temporary folder used to create USB key to create directory tree 
 
-Be careful : if ``-d`` parameter is define then the usb key / external drive 
-will be erased.
+Be careful : if ``-d`` parameter is define then the relative peripheral will 
+be erased
 
-Since syslinux files are placed differently depending on the distribution,
- configuration file (``-c``) contain directory to syslinux files :
- 
- * __syslinux_mbr_bl_folder__ : folder containing mbr.bin
- * __syslinux_efi_bl_folder__ : folder containing efi64 folder
- * __syslinux_modules_folder__ : folder containing syslinux modules folders
+For now, this script doesn't verify the state of your device (is mounted or not)
+ but this is planned.
 
-## Examples
+## Exemples
 
-Prepare file in directory for efi system without writing an usb key for AMD64.
+Prepare file in directory for efi system without writing an usb key for AMD64 arch.
 
 ```
 ./init.sh
 ```
 
-Prepare an USB key (/dev/sdb) for bios / i386 architecture
+Prepare an usb key (/dev/sdb) for bios / i386 architecture
 
 ```
 ./init.sh -a i386 -b -d /dev/sdb
 ```
-
-Prepare an USB key on Debian
-
-```
-./init.sh -d /dev/sdb -c conf/debian.conf
-```
-
-# How it work
-
- 1. Create a repo folder then a subfolder named with debian version then 
-    download debian iso, vmlinuz and initrt.gz.
- 2. Create a temporary folder and copy all necessary files into it (pressed,
-    partman recipes, syslinux modules...).
- 4. If ``-d /dev/sdx``, unmount usb key( if mounted) and create partition scheme,
-    format and  mount partitions.
- 5. Copy all content of temporary folder into mounted usb key.
- 6. Unmount usb key.
