Of course it shouldn't be a complete howto. But it should at least be helpful, and indeed as a developer it's not obvious what is not clear. I can't provide the text, cause I don't know what the various options do. I found good (openSUSE) documentation here: https://doc.opensuse.org/documentation/leap/reference/html/book.opensuse.reference/cha.grub2.html#sec.grub2.etc_grub_d I just opened to small bug reports for the documentation: 1017720 and 1017726. To start with would it be possible to refer from the help to this documentation, that would be already be helpful.
