  --no-config              Do not look for a configuration file.
  --find-config-path <path>
                           Finds and prints the path to a configuration file for a given input file.
  --ignore-path <path>     Path to a file containing patterns that describe files to ignore.
                           Defaults to ./.prettierignore.
