I tried to cross reference with the syslinux wik, for isolinux
http://www.syslinux.org/wiki/index.php?title=ISOLINUX, but it was just
as unclear. It was using mkisofs as well.

There are two parts that are unclear. Where and what isolinux files to
put on the directory tree I want to turn into a bootable iso and what
command to run to convert the directory tree into a bootable iso image.

There are some miscellaneous things such as syslinux configs and using a
squashfs root operating system volume, but I can solve that myself via
trial and error after these show stoppers are out of the way.
