 - **QR Codes**: Automatisch gegenereerde QR codes voor elk onderdeel, met printbare stickers.
 - **Meertalig**: Ondersteuning voor Nederlands en Engels.
-- **Real-time Updates**: Boom navigatie wordt automatisch bijgewerkt na CRUD operaties.
 
 ## Installatie
 
 1. Zorg voor een LXC container 'www' met Apache, PHP, en Composer.
-2. Clone de repository naar `/var/www/localhost` in de container.
+2. Clone de repository naar /var/www/localhost in de container.
 3. Run `composer install` in de container.
 4. Stel de database in: `collections.sqlite` wordt automatisch aangemaakt.
-5. Configureer Apache om als `ubuntu` gebruiker te draaien (zie Apache Configuratie).
-6. Start Apache en ga naar http://localhost.

-## Apache Configuratie
-
-De applicatie draait met Apache als `ubuntu` gebruiker voor development:
-
-```bash
-# Apache gebruiker instellen
-sudo nano /etc/apache2/envvars  # Wijzig APACHE_RUN_USER=ubuntu
-sudo nano /etc/apache2/apache2.conf  # Wijzig User/Group naar ubuntu
-sudo systemctl restart apache2
-
-# Permissions instellen
-sudo chown -R ubuntu:ubuntu /var/www/localhost
-sudo chmod 755 /var/www/localhost/public/js/
-sudo chmod 644 /var/www/localhost/public/js/*

 ## Ontwikkeling
 
-- **Dependencies**: `composer install` / `update`
-- **Linting**: Volg PSR-12 handmatig
-- **Testing**: `curl localhost` of `php test.php` voor individuele tests
-- **Database**: Gebruik `App\Database\Database::getInstance()` (geen directe PDO)
-- **I18n**: `App\Services\TranslationService` (PHP) of `{{ trans('ID') }}` (Twig)
-- **Commits**: Elke wijziging heeft een git commit
-
-## Code Conventies
-
-- **Architecture**: MVC patroon met PSR-4 namespacing
-- **Naming**: Classes `PascalCase`, methods/variables `camelCase`
-- **Templating**: Alleen Twig (`.twig` files)
-- **Security**: Geen secrets/keys in code of logs
-- **Types**: Type hints waar mogelijk
-- **Comments**: Vermijd tenzij gevraagd
+- **Linting**: Geen specifieke tool, volg PSR-12.
+- **Testing**: Geen tests, gebruik curl voor API testing.
+- **Commits**: Elke wijziging heeft een git commit.
