 Welcome ! It seems you are intrested in my Melon OS...
 
 ** HOW TO BUILD MELON : **
+This is supposed to work in a Linux environment. Maybee it could work on *BSD, or Cygwin, but that wasn't tested.
 
 If you haven't yet downloaded the source code, then commit the GIT repository :
 $ git clone git://github.com/Alexis211/Melon.git

 Create the floppy image :
 $ make floppy
+You will probably be prompted for your password. We need it to mount the floppy image as a loopback device.
 
 And run it with Qemu :
 $ make qemu
