Laravel-4 cron jobs

I need to learn how to work with cron jobs in Laravel..As I can see the documentation does not specify this part.I have found a tutorial but it is about Laravel-3. Can you give me some advice on how to schedule a cron job running once a day..?Is there any tutorial about that issue?

My code so far is the following :

JobDaemon.php :

<?php

use Illuminate\Console\Command;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Input\InputArgument;

class JobDaemon extends Command {

    /**
     * The console command name.
     *
     * @var string
     */
    protected $name = 'job-daemon';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Get all recent jobs once a day.';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return void
     */
    public function fire()
    {
        $this->info('fired');
    }

    /**
     * Get the console command arguments.
     *
     * @return array
     */
    protected function getArguments()
    {
        return array(
            //array('example', InputArgument::REQUIRED, 'An example argument.'),
        );
    }

    /**
     * Get the console command options.
     *
     * @return array
     */
    protected function getOptions()
    {
        return array(
            //array('example', null, InputOption::VALUE_OPTIONAL, 'An example option.', null),
        );
    }

}

I used the following command to set it up

php artisan command:make JobDaemon

And my artisan file is the following:

<?php

Artisan::add(new JobDaemon);

I get the following from my console...
