Description:

def note(name, source=None, contents=None, **kwargs):
    '''
    Add content to a document generated using `highstate_doc.render`.

    This state does not preform any tasks on the host. It only is used in highstate_doc lowstate proccessers
    to include extra documents.

    .. code-block:: yaml

        {{sls}} example note:
            highstate_doc.note:
                - name: example note
                - require_in:
                    - pkg: somepackage
                - contents: |
                    example `highstate_doc.note`
                    ------------------
                    This state does not do anything to the system! It is only used by a `proccesser`
                    you can use `requisites` and `order` to move your docs around the rendered file.
                    .. this message appare aboce the `pkg: somepackage` state.
