-- **Deploy**: Le cartelle vengono caricate direttamente su web server Apache.
+- **Dipendenze**: dalla root del repository eseguire `composer install --optimize-autoloader` oppure `composer-install.bat`.
+- **Deploy**: Eseguire `composer install --no-dev --optimize-autoloader` e caricare sul server sia `php/` sia `vendor/`, mantenendole allo stesso livello.
 - **Server locale**:
   - **PHP CLI**: Avviare il server dalla cartella `php/` tramite `php -S localhost:8080` (le pagine saranno raggiungibili su `http://localhost:8080/<nome-pagina>/`).
   - **Docker**: Dalla root del repository, eseguire:
     ```bash
