Missing addAlternate example in the README

[pavlov80]

Looks like these parts of the README file are the same. I want to see the documentation how to use addAlternate for multiple languages.

Manually adding links
You can manually add links to a sitemap:

use Spatie\Sitemap\SitemapGenerator;
use Spatie\Sitemap\Tags\Url;

SitemapGenerator::create('https://example.com')
->getSitemap()
// here we add one extra link, but you can add as many as you'd like
->writeToFile($sitemapPath);
Adding alternates to links
Multilingual sites may have several alternate versions of the same page (one per language). Based on the previous example adding an alternate can be done as follows:

use Spatie\Sitemap\SitemapGenerator;
use Spatie\Sitemap\Tags\Url;

SitemapGenerator::create('https://example.com')
->getSitemap()
// here we add one extra link, but you can add as many as you'd like
->writeToFile($sitemapPath);
Note the addAlternate function which takes an alternate URL and the locale it belongs to.

Have you figured it out by now?
If not:

SitemapGenerator::create(config('app.url'))
    ->getSitemap()
    ->add(
        Url::create(route('en.home'))
        ->setLastModificationDate(now())
        ->addAlternate(route('nl.home'), 'nl'));
    ->writeToFile(public_path('sitemap.xml'));

Change the route(..) function to any URL you like, and you can leave the locale empty too. Don't know (yet) what it does without locale.

I use something like this right now:

SitemapSpatie::create()
    ->add(
        collect($chunk)->map(function ($url) {
            $link = Url::create($url);


             foreach ($languages as $lang) {
                $link = $link->addAlternate(
                    LaravelLocalization::localizeUrl($url, $lang),
                    $lang
                );
             }

            $link = $link->addAlternate(LaravelLocalization::localizeUrl($url, $lang), $lang);
            $link = $link->addImage(asset("path_to_image"));
      
            return $link;
        })->toArray()
    )
    ->writeToFile($sitemapPath);
