If you are doing some quick tests with Apache, you can also run

``composer require symfony/apache-pack``. This package creates an ``.htaccess``

file in the ``public/`` directory with the necessary rewrite rules needed to serve

the Symfony application. However, in production, it's recommended to move these

rules to the main Apache configuration file (as shown above) to improve performance.

for that directory; otherwise, the ``.htaccess`` file will be ignored.
