});
parser.addArgument(['-o', '--output'], {
  help: 'Path to the resulting md file',
  metavar: '',
  dest: 'output'
});
parser.addArgument(['--skip-info'], {
  action: Action.storeTrue,
  nargs: 0,
  help: 'Skip the title, description, version etc, whatever is in the info block.',
  metavar: '',
  dest: 'skipInfo'
});
const args = parser.parseArgs();

if (args.input) {
  const document = [];

  try {
    const inputDoc = yaml.safeLoad(fs.readFileSync(args.input, 'utf8'));
    const outputFile = args.output || args.input.replace(/(yaml|yml|json)$/i, 'md');

    const parameters = ('parameters' in inputDoc) ? inputDoc.parameters : {};
