use Lemonade\Meta\MetaData;
use Lemonade\Meta\MetaFactory;

// 1. Prepare meta data
// Create a data object that contains all information for SEO and social networks.
$data = new MetaData(
    websiteName: "Lemonade Framework",
    title: "Knihovna pro meta tagy",

);

// 2. Create a factory instance for generating tags
// Pass in the prepared data.
$metaFactory = new MetaFactory($data);

// 3. Generate and output HTML code
// MetaFactory implements Stringable, so you can echo it directly
echo $metaFactory;
