            if None, the values are
            ['Args', 'Arguments', 'Attention', 'Attributes', 'Caution', 'Danger',
             'Error', 'Example', 'Examples', 'Example Request', 'Hint', 'Important', 'Keyword Args',
             'Keyword Arguments', 'Kwargs', 'Methods', 'Note', 'Notes', 'Other Parameters',
             'Parameters', 'Return', 'Returns', 'Raises', 'References', 'See Also',

                 - section_body (str)
            - parameters (List[Dict]) : the list of each parameter, each parameter is composed of five keys,
