ostree hook for mkinitcpio contain no help

[JotaRandom]

the ostree hook shipped within usr/lib/initcpio/install/ostree which i'm sure is src/boot/mkinitcpio/ostree contain no help or information at all, this is evident when you run mkinitcpio -H ostree and just give ==> ERROR: No help for hook ostree, this can be fixed giving a help in the hook

this is an example of base hook:

#!/usr/bin/env bash
# SPDX-License-Identifier: GPL-2.0-only

build() {
    local applet

    for applet in $(/usr/lib/initcpio/busybox --list); do
        add_symlink "/usr/bin/$applet" busybox
    done

    add_binary /usr/lib/initcpio/busybox /bin/busybox

    # add kmod with applet symlinks
    add_binary kmod
    for applet in {dep,ins,rm,ls}mod mod{probe,info}; do
        add_symlink "/usr/bin/$applet" kmod
    done

    add_binary blkid
    map add_binary mount umount
    add_binary switch_root

    add_binary "/usr/lib/initcpio/init_functions" "/init_functions"
    add_binary "/usr/lib/initcpio/init" "/init" 755
}

help() {
    cat <<HELPEOF
This hook provides crucial runtime necessities for booting. DO NOT
remove this hook unless you know what you're doing.

}

# vim: set ft=sh ts=4 sw=4 et:

while this is the ostree hook

#!/bin/bash

build() {
    add_binary /usr/lib/ostree/ostree-prepare-root
    add_binary /usr/lib/ostree/ostree-remount

    add_file /usr/lib/systemd/system/ostree-prepare-root.service
    add_symlink /usr/lib/systemd/system/initrd-root-fs.target.wants/ostree-prepare-root.service \
        /usr/lib/systemd/system/ostree-prepare-root.service
}

in the actual state i don't even know what its does, where on bethwheen which hook i can place it or what does.
