// Adding flags
cli.StringFlag("config", "Path to config file", &configPath)
cli.BoolFlag("verbose", "Enable verbose output", &verbose)
cli.IntFlag("port", "Port to listen on", &port)

// Adding a subcommand
cmd := cli.NewSubCommand("start", "Start the application")
cmd.Action(func() error {
    // Command logic here
    return nil
})

// Run the CLI
if err := cli.Run(); err != nil {
    log.Fatal(err)
}
