It should still be mentioned.

If you want to say "for information about OTHER user-level
commands" or "for more information about these user-level
commands" (depending on which is meant), that would be fine, but
as it stands now it is confusing and misleading, giving
the impression that what are described here might NOT be
user-level commands.
