 mkinitcpio-ykfde
 ================
 
-Full disk encryption with Yubikey (Yubico key)
+**Full disk encryption with Yubikey (Yubico key)**
+
+This allows to automatically unlock a LUKS encrypted hard disk from `systemd`-
+enabled initramdfs.
+
+Requirements
+------------
+
+To compile and use yubico full disk encryption you need:
+
+* [iniparser](http://ndevilla.free.fr/iniparser/)
+* [systemd](http://www.freedesktop.org/wiki/Software/systemd/)
+* [mkinitcpio](https://projects.archlinux.org/mkinitcpio.git/) (Though
+  it may be easy to port this to any initramfs that uses systemd)
+* [markdown](http://daringfireball.net/projects/markdown/) (HTML documentation)
+
+Additionally it is expected to have `make` and `pkg-config` around to
+successfully compile.
+
+Build and install
+-----------------
+
+Building and installing is very easy. Just run:
+
+> make
+
+followed by:
+
+> make install
+
+This will place file to their desired places in filesystem.
+
+Usage
+-----
+
+First prepare the key. Plug it in, make sure it is configured for HMAC-
+SHA1, then run:
+
+> ykfde -d /dev/`LUKS-device`
+
+This will add a new slot to your LUKS device. Add `ykfde` to your hook
+list in `/etc/mkinitcpio.conf` and rebuild your initramfs with:
+
+> mkinitcpio -p linux
+
+Reboot and have fun!
