+This hook allows for an encrypted root device. Users should specify the device
+to be unlocked using 'cryptdevice=device:dmname' on the kernel command line,
+where 'device' is the path to the raw device, and 'dmname' is the name given to
+the device after unlocking, and will be available as /dev/mapper/dmname.
+
+For unlocking via keyfile, 'cryptkey=device:fstype:path' should be specified on
+the kernel cmdline, where 'device' represents the raw block device where the key
+exists, 'fstype' is the filesystem type of 'device' (or auto), and 'path' is
+the absolute path of the keyfile within the device.
+
+Without specifying a keyfile, you will be prompted for the password at runtime.
+This means you must have a keyboard available to input it, and you may need
+the keymap hook as well to ensure that the keyboard is using the layout you
+expect.
