If you want to automate the process, then use one of the publishers.
Install the package
All you need to do to get started is add Laravel Lang to your composer dependencies:
composer require laravel-lang/lang --dev
When installing the package this way, you will need to manually copy the files from the
vendor/laravel-lang/lang folder into your application.
But you won’t be able to just put the files, because. Laravel structure is different. Therefore, you will need to either manually update your PHP and JSON files, replacing the keys in them, or use a publisher.
