+Compiling HDT
+--------------
+To build HDT, you just have to do a "make" call in this directory.
+
+---------------------------
+Creating a bootable floppy
+--------------------------
+To build a bootable HDT floppy image, you can do a "make hdt.img" call.
+This will requires the mtools (http://mtools.linux.lu) to be installed.
+The script will try to pick several files from your system :
+- /lib/modules/`uname -r`/modules.alias
+- /lib/modules/`uname -r`/modules.pcimap
+- /usr/share/pci.ids or /usr/share/hwdata/pci.ids
+
+This paths can be overrided with the following command line:
+make MODULES_ALIAS_FILE=$(PWD)/floppy/modules.alias MODULES_PCIMAP_FILE=$(PWD)/floppy/modules.pcimap PCI_IDS_FILE=$(PWD)/floppy/pci.ids hdt.img
+
+If your system doesn't have pci.ids, please download it from http://pciids.sourceforge.net/ and put it into the floppy/ directory.
