+# WEBSHOP SYSTEM - API DOKUMENTATION
+
+## ÜBERBLICK
+
+Das Webshop-System bietet eine vollständig PrestaShop-kompatible API mit erweiterten Funktionen für moderne E-Commerce-Anwendungen.
+
+**Version:** 1.0.0  
+**Basis:** PrestaShop 8.x kompatibel  
+**Lizenz:** GPL v3  
+**Autor:** Webshop System
+
+## 🚀 SCHNELLSTART
+
+### Installation
+
+```bash
+# Repository klonen
+git clone https://github.com/webshop-system/core.git
+
+# Dependencies installieren
+composer install
+
+# Docker-Container starten
+docker-compose up -d
+
+# Datenbank initialisieren
+php bin/console doctrine:database:create
+php bin/console doctrine:migrations:migrate
+```
+
+### Erste Schritte
+
+```php
+// Context initialisieren
+$context = Context::getContext();
+
+// Produkt erstellen
+$product = new Product();
+$product->name = 'Mein Produkt';
+$product->price = 29.99;
+$product->add();
+
+// Produkt abrufen
+$product = new Product(1);
+echo $product->name; // "Mein Produkt"
+```
+
+## 📚 CORE-KLASSEN

+```
+
+#### Hauptmethoden
+
+**Produkt erstellen:**
+```php
+$product = new Product();
+$product->name = 'Produktname';
+$product->reference = 'REF-001';
+$product->price = 29.99;
+$product->active = true;
+$result = $product->add();

+
+echo "✅ Deployment abgeschlossen!"
+```
+
+## 📊 PERFORMANCE-OPTIMIERUNG
+
+### Caching-Strategien
+
+```php
+// Redis-Cache konfigurieren
+Cache::setRedisConnection([
+    'host' => 'redis',
+    'port' => 6379,
+    'database' => 0
+]);
+
+// Produkt-Cache
+$product = Cache::retrieve('product_1');
+if (!$product) {
+    $product = new Product(1);
+    Cache::store('product_1', $product, 3600);
+}
+```
+
+### Datenbank-Optimierung
+
+```sql
+-- Indizes für bessere Performance
+CREATE INDEX idx_product_active ON product(active);
+CREATE INDEX idx_product_category ON product(id_category_default);
+CREATE INDEX idx_product_price ON product(price);
+CREATE INDEX idx_order_customer ON `order`(id_customer);
+CREATE INDEX idx_cart_customer ON cart(id_customer);
+```
+
+### Monitoring
+
+```php
+// Performance-Monitoring
+$startTime = microtime(true);
+$product = new Product(1);
+$endTime = microtime(true);
+
+$executionTime = $endTime - $startTime;
+Logger::log('Product load time: ' . $executionTime . 's');
+```
+
+## 🔒 SICHERHEIT
+
+### Validierung
+
+```php
+// Input-Validierung
+$name = Tools::safeOutput($_POST['name']);
+$email = Validate::isEmail($_POST['email']);
+$price = Validate::isPrice($_POST['price']);
+
+if (!$email) {
+    throw new Exception('Ungültige E-Mail-Adresse');
+}
+```
+
+### SQL-Injection-Schutz
+
+```php
+// Sichere Queries
+$sql = 'SELECT * FROM product WHERE id = ' . (int)$id;
+$sql = 'SELECT * FROM product WHERE name = \'' . pSQL($name) . '\'';
+```
+
+### XSS-Schutz
+
+```php
+// Output-Escaping
+echo Tools::safeOutput($userInput);
+echo htmlspecialchars($userInput, ENT_QUOTES, 'UTF-8');
+```
+
+## 🧪 TESTING
+
+### Unit-Tests ausführen
+
+```bash
+# Alle Tests
+vendor/bin/phpunit
+
+# Spezifische Test-Klasse
+vendor/bin/phpunit tests/Unit/ProductTest.php
+
+# Mit Coverage-Report
+vendor/bin/phpunit --coverage-html coverage/
+```
+
+### Integration-Tests
+
+```php
+// Beispiel Integration-Test
+class OrderIntegrationTest extends TestCase
+{
+    public function testCompleteOrderFlow()
+    {
+        // Kunde erstellen
+        $customer = new Customer();

+        $order->add();
+
+        $this->assertGreaterThan(0, $order->id);
+    }
+}
+```
+
+## 📈 MONITORING & LOGGING
+
+### Logging-Konfiguration
+
+```php
+// Logger konfigurieren
+Logger::setLogLevel(Logger::INFO);
+Logger::log('Application started', Logger::INFO);
+Logger::log('Error occurred', Logger::ERROR);
+```
+
+### Performance-Monitoring
