# Customizing the metatags
## Adding metatags
To add new `` meta tags, you can use the `sylius_admin#metatags` hook. This is useful for adding a favicon or SEO meta tags, for example. You can register your own Twig template for meta tags via YAML or PHP.
{% tabs %}
{% tab title="YAML" %}
{% code title="config/packages/sylius\_bootstrap\_admin\_ui.yaml" lineNumbers="true" %}
```yaml
# ...
sylius_twig_hooks:
hooks:
# ...
'sylius_admin.base#metatags':
favicon:
template: 'favicon.html.twig'
seo_metatags:
template: 'seo_metatags.html.twig'
```
{% endcode %}
{% endtab %}
{% tab title="PHP" %}
{% code title="config/packages/sylius\_bootstrap\_admin\_ui.php" lineNumbers="true" %}
```php
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;
return static function (ContainerConfigurator $containerConfigurator): void {
// ...
// Define your own Twig template for the favicon.
$containerConfigurator->extension('sylius_twig_hooks', [
'hooks' => [
'sylius_admin.base#metatags' => [
'favicon' => [
'template' => 'favicon.html.twig',
],
'seo_metatags' => [
'template' => 'seo_metatags.html.twig',
],
],
],
]);
};
```
{% endcode %}
{% endtab %}
{% endtabs %}
{% code title="templates/favicon.html.twig" %}
```twig
```
{% endcode %}
{% code title="templates/seo\_metatags.html.twig" %}
```twig
```
{% endcode %}
