Asciidoc NOTE macro here?

See also that NOTE:

    *NOTE*: Do *not* use this option unless you have read the note
    for linkgit:git-clone[1]'s `--reference`, `--shared`, and `--dissociate`
    options carefully.

    `--dissociate`::
            This option is only valid for add and update commands.  These
            commands sometimes need to clone a remote repository. In this case,
            this option will be passed to the linkgit:git-clone[1] command.
    +
    *NOTE*: see the NOTE above for the `--reference` option.
