# Help

Caporal automatically generates help/usage instructions for you. Help can be displayed using -h or --help options, or with the default help command.

You can add some custom help to the whole program or to specific commands using .help(text, options).

The text, even if multi-line, will be automatically indented. Multiple help sections with custom names are supported.

# Customizing help for the whole program

# program.help(text: string, options?: CustomizedHelpOpts)

Options properties available here.

#!/usr/bin/env node
const program = require("caporal")
program
  .version("1.0.0")
  // our custom help for the whole program
  .help("my global help")
  .command("order pizza")
  .action(function (args, options) {})

program.run()
