Configure Help option with commad that takes one argument in node commander

Question

How to configure help option the command in node commander that takes one argument.
Like, I have one command to add-repository as below:

program
  .command('add-repository <repo-name>')
  .option('-h,--help','help add-repository command')
  .description('configure your repository to do the respository specific taks')
  .action(addRepoCommandHandler);

Currently I can call the command by specifying the argument and it is working fine. I want to add one option to add help option. That will show the help text when user calls the command with -h or --help option like: add-repository --help.

By default every command has a help option. So just take out your own help option and try using the one Commander adds for you.

You may change the default help flags and description using .helpOption().
