+## 🎯 Was Sie damit erreichen
+
+### Vor der Integration
+```
+Scraper (standard)
+  └─ Ein einzelner Browser ohne IP-Rotation
+     └─ Alle Requests von gleicher IP
+        └─ Risiko: IP-Block durch Zielwebsite
+```
+
+### Nach der Integration
+```
+Scraper mit ProtonVPN
+  ├─ Session 1 (US, IP: 1.2.3.4)
+  │  ├─ Task 1, 2, 3, 4, 5 (gleiche IP)
+  │  └─ Perfekt für: Zusammenhängende Data
+  │
+  ├─ Session 2 (UK, IP: 5.6.7.8)
+  │  ├─ Task 6, 7, 8, 9, 10 (gleiche IP)
+  │  └─ Perfekt für: Mehrstufige Extraktion
+  │
+  └─ Session 3 (JP, IP: 9.10.11.12)
+     ├─ Task 11, 12, 13, 14, 15 (gleiche IP)
+     └─ Perfekt für: Diverse geografische Daten
+```
+
+### Ergebnisse
+- ✅ **IP-Rotation:** Automatisch zwischen Sessions
+- ✅ **Flexibel:** Konfigurierbar wie viele Tasks pro IP
+- ✅ **Zuverlässig:** Automatische VPN-Verbindung & Überprüfung
+- ✅ **Monitörbar:** Strukturiertes Logging aller Operationen
+- ✅ **Wartbar:** Sauberer, modularer Code

+## 💻 Technische Highlights
+
+### Modular & Flexibel
+```rust
+// Easy to enable/disable
+ENABLE_VPN_ROTATION=false  // Alle VPN-Komponenten deaktiviert
+
+// Easy to configure
+VPN_SERVERS=US,UK,JP       // Beliebig viele Server
+TASKS_PER_VPN_SESSION=10   // Flexible Rotation
+```
+
+### Production-Ready Code
+- Fehlerbehandlung mit aussagekräftigen Kontexten
+- Asynchrone, non-blocking Operations
+- Structured Logging für Debugging
+- Unit Tests für kritische Funktionen
+
+### Zero Additional Dependencies
+- Nutzt bereits vorhandene Crates: `tokio`, `fantoccini`, `serde`, `anyhow`, `tracing`
+- Keine neuen, externen Abhängigkeiten erforderlich
+
+---
+
+## 🧪 Wie man testen kann
+
+### Ohne VPN (Baseline)
+```bash
+ENABLE_VPN_ROTATION=false MAX_PARALLEL_TASKS=1 cargo run
+# Schnell, keine VPN-Logs
+```
+
+### Mit VPN, langsam (zum Debuggen)
+```bash
+ENABLE_VPN_ROTATION=true VPN_SERVERS=US TASKS_PER_VPN_SESSION=5 \
+MAX_PARALLEL_TASKS=1 RUST_LOG=debug cargo run
+```
+
+### Mit VPN, parallel (Production)
+```bash
+ENABLE_VPN_ROTATION=true VPN_SERVERS=US,UK,JP \
+TASKS_PER_VPN_SESSION=20 MAX_PARALLEL_TASKS=3 cargo run
+```

+
+## 🔑 Wichtige Konzepte
+
+### Session
+Eine Periode, in der Browser-Traffic durch einen ProtonVPN-Server geleitet wird (gleiche IP).
+
+### Task-Counter
+Zählt Aufgaben pro Session. Nach Erreichen des Limits: Neue Session mit neuer IP.
+
+### Extension-Automater
+Automatisiert die ProtonVPN Chrome-Extension UI für:
+- Verbindung trennen/verbinden
+- Server auswählen
+- IP-Überprüfung
+
+### VpnIntegration
+High-Level API für einfache Verwendung in Ihren Modulen.

+
+---
+
+## 📊 Erfolgs-Metriken
+
+Nach erfolgreicher Integration sollten Sie sehen:
+
+✅ **Logs wie diese:**
+```
+✓ Created new VPN session: session_US_1702123456789
+🔗 Connecting to ProtonVPN server: US
+✓ Successfully connected to US after 3500 ms
+📍 Current external IP: 192.0.2.42
+✓ Task 1/100 completed in session session_US_1702123456789
+```
+
+✅ **Config funktioniert:**
+```
+ENABLE_VPN_ROTATION=true
+VPN_SERVERS=US,UK,JP
+TASKS_PER_VPN_SESSION=10
+```
+
+✅ **Verschiedene IPs pro Session:**
+```
+Session 1 (US):   IP 192.0.2.1   (Tasks 1-10)
+Session 2 (UK):   IP 198.51.100.1 (Tasks 11-20)
+Session 3 (JP):   IP 203.0.113.1  (Tasks 21-30)
+```
+
+---
+
+## ⚠️ Wichtige Hinweise
+
+1. **Extension-UI kann sich ändern**
+   - Prüfen Sie XPath-Selektoren nach Extension-Updates
+   - Siehe: TROUBLESHOOTING_DE.md
+
+2. **VPN braucht Zeit**
+   - 2-3 Sekunden zum Disconnect/Connect
+   - Timeouts in Code berücksichtigen
+
+3. **Browser muss sichtbar sein**
+   - Headless-Mode funktioniert teilweise nicht
+   - Für Tests: `--headless=false` verwenden
+
+4. **IP-Rotation nicht garantiert**
+   - ProtonVPN mit Load-Balancing kann ähnliche IPs haben
+   - Aber typischerweise unterschiedlich genug für Scraping

+
+### Konfiguration
+
+Alle VPN-Einstellungen erfolgen über `.env`:
+
+```env
+# VPN aktivieren
+ENABLE_VPN_ROTATION=true
+
+# Server-Liste (komma-separiert)
+VPN_SERVERS=US-Free#1,UK-Free#1,JP-Free#1
+
+# Tasks pro Session (0 = zwischen Phasen rotieren)
+TASKS_PER_VPN_SESSION=5
+
+# Extension-ID (Standard: offizielle ProtonVPN)
+PROTONVPN_EXTENSION_ID=ghmbeldphafepmbegfdlkpapadhbakde
+```
+
+---
+
+## 🚀 Schnellstart
+
+### 1. Konfiguration einrichten
+```bash
+cp .env.example .env
+# Öffnen Sie .env und aktivieren Sie VPN

+
+## 🔑 Hauptkomponenten
+
+### 1. VpnSessionManager (`vpn_session.rs`)
+Verwaltet VPN-Sessions mit Server-Rotation:
+- Server-Liste durchlaufen (round-robin)
+- Task-Counter pro Session
+- Automatische Rotation wenn Limit erreicht
+
+```rust
+let manager = VpnSessionManager::new(
+    vec!["US", "UK", "JP"],
+    5  // 5 Tasks pro Session
+);
+
+manager.create_new_session().await?;
+manager.increment_task_count().await;
+if manager.should_rotate().await {
+    // Neue Session erstellen
+}
+```
+
+### 2. ProtonVpnAutomater (`protonvpn_extension.rs`)
+Automatisiert die ProtonVPN-Extension-UI:
+- Verbindung trennen
+- Mit Server verbinden
+- VPN-Status überprüfen
+- IP-Adresse abrufen
+
+```rust
+let automater = ProtonVpnAutomater::new("extension-id");
+automater.connect_to_server(&client, "US").await?;
+let ip = automater.get_current_ip(&client).await?;
+```
+
+### 3. VpnIntegration (`vpn_integration.rs`)
+Vereinfachte High-Level API für Module:
+- Initialisierung aus Config
+- Session-Rotation prüfen & durchführen
+- Task-Counter verwalten
+
+```rust
+let vpn = VpnIntegration::from_config(&config)?;
+
+if vpn.check_and_rotate_if_needed().await? {
+    // Neue Session erstellt
+}
+vpn.increment_task().await;
+```
+
+---
+
+## 📝 Integrations-Anleitung
+
+### Schritt 1: VpnIntegration in main.rs
+
+```rust
+use scraper::vpn_integration::VpnIntegration;
+
+#[tokio::main]
+async fn main() -> Result<()> {
+    let config = Config::load()?;
+    let vpn = VpnIntegration::from_config(&config)?;
+    let pool = Arc::new(ChromeDriverPool::new(config.max_parallel_tasks).await?);
+
+    // Initiale Session
+    if vpn.enabled {
+        vpn.initialize_session().await?;
+    }
+
+    // Updates mit VPN
+    economic::run_full_update(&config, &pool, &vpn).await?;
+    corporate::run_full_update(&config, &pool, &vpn).await?;
+
+    Ok(())
+}
+```
+
+### Schritt 2: Economic/Corporate Module aktualisieren
+
+```rust
+// src/economic/mod.rs
+pub async fn run_full_update(
+    config: &Config,
+    pool: &Arc<ChromeDriverPool>,
+    vpn: &scraper::vpn_integration::VpnIntegration,
+) -> Result<()> {
+    for task in tasks {
+        if vpn.check_and_rotate_if_needed().await? {
+            tokio::time::sleep(Duration::from_secs(2)).await;
+        }
+        
+        // Task ausführen
+        
+        vpn.increment_task().await;
+    }
+    Ok(())
+}
+```
+
+---
+
+## 🧪 Testing
+
+### Test 1: Ohne VPN (Baseline)
+```bash
+ENABLE_VPN_ROTATION=false MAX_PARALLEL_TASKS=1 cargo run
+```
+
+### Test 2: Mit VPN, langsam
+```bash
+ENABLE_VPN_ROTATION=true VPN_SERVERS=US MAX_PARALLEL_TASKS=1 TASKS_PER_VPN_SESSION=5 RUST_LOG=debug cargo run
+```
+
+### Test 3: Mit VPN, parallel
+```bash
+ENABLE_VPN_ROTATION=true VPN_SERVERS=US,UK,JP MAX_PARALLEL_TASKS=3 TASKS_PER_VPN_SESSION=10 cargo run
+```
+
+### Unit Tests
+```bash
+cargo test scraper::vpn_session
+cargo test scraper::protonvpn_extension
+```

+
+## ✅ Checkliste für Implementierung
+
+- [ ] `.env.example` gelesen
+- [ ] ProtonVPN-Extension installiert
+- [ ] Extension-ID überprüft & in `.env` eingetragen
+- [ ] `src/scraper/` Module kopiert
+- [ ] `src/config.rs` aktualisiert
+- [ ] `src/scraper/mod.rs` aktualisiert
+- [ ] `cargo build --release` ohne Fehler
+- [ ] Test ohne VPN: `ENABLE_VPN_ROTATION=false cargo run`
+- [ ] Test mit VPN: `ENABLE_VPN_ROTATION=true RUST_LOG=debug cargo run`
+- [ ] Economic/Corporate Module angepasst
+- [ ] Unit Tests laufen: `cargo test`
+- [ ] Logging getestet: `RUST_LOG=info cargo run`
+
+---
+
+## 🚨 Wichtige Hinweise
+
+⚠️ **Extension UI-Selektoren können veränderlich sein**
+- Prüfen Sie regelmäßig mit Chrome DevTools (F12)
+- Aktualisieren Sie XPath bei Extension-Updates
+
+⚠️ **VPN-Verbindung braucht Zeit**
+- 2-3 Sekunden zum Trennen/Verbinden einplanen
+- Timeouts in Code berücksichtigen
+
+⚠️ **Browser muss für UI-Automatisierung sichtbar sein**
+- Headless-Mode funktioniert teilweise nicht
+- Bei Tests: `--headless=false` verwenden
+
+⚠️ **IP-Rotation ist nicht garantiert**
+- ProtonVPN-Server mit Load-Balancing können ähnliche IPs haben
+- Aber typischerweise unterschiedlich genug für Website-Scraping
+
+---
+
+## 🎯 Nächste Schritte
+
+1. **Sofort:**
+   - `.env` vorbereiten
+   - ProtonVPN Extension installieren
+   - `cargo build` testen
+
+2. **Diese Woche:**
+   - Integration in Economic Module
+   - Integration in Corporate Module
+   - Performance-Tests mit verschiedenen Konfigurationen
+
+3. **Später:**
+   - Monitoring Dashboard für VPN-Sessions
+   - Analytics für IP-Rotation
+   - Alternative Proxy-Support (optional)

+# ProtonVPN-Integration für WebScraper: Quick-Start Guide
+
+## 🚀 Schnelleinstieg (5 Minuten)
+
+### 1. Konfiguration vorbereiten
+```bash
+# Copy .env.example zu .env
+cp .env.example .env
+
+# Öffnen Sie .env und aktivieren Sie VPN:
+# ENABLE_VPN_ROTATION=true
+# VPN_SERVERS=US-Free#1,UK-Free#1,JP-Free#1
+# TASKS_PER_VPN_SESSION=5
+```
+
+### 2. ProtonVPN-Extension installieren
+```bash
+# A. Automatisch (empfohlen):
+# Chrome öffnet die Extension automatisch beim ersten Browser-Start
+
+# B. Manuell:
+# 1. Chrome öffnen
+# 2. chrome://extensions/ öffnen
+# 3. "ProtonVPN by Proton Technologies AG" suchen
+# 4. Installieren & Anmelden mit ProtonVPN-Account
+```
+
+### 3. Extension-ID überprüfen
+```bash
+# 1. Chrome → chrome://extensions/
+# 2. ProtonVPN Details klicken
+# 3. Extension ID kopieren
+# 4. In .env eintragen:
+#    PROTONVPN_EXTENSION_ID=ghmbeldphafepmbegfdlkpapadhbakde
+```
+
+### 4. Cargo.toml überprüfen
+```toml
+[dependencies]
+fantoccini = { version = "0.20", features = ["rustls-tls"] }
+tokio = { version = "1.38", features = ["full"] }
+tracing = "0.1"
+tracing-subscriber = { version = "0.3", features = ["fmt", "env-filter"] }
+```
+
+### 5. Projekt kompilieren & testen
+```bash
+# Kompilierung
+cargo build --release
+
+# Mit Logging starten
+RUST_LOG=info cargo run
+
+# Mit Debug-Logging:
+RUST_LOG=debug cargo run
+```

+## 🐛 Häufigste Fehler & Lösungen
+
+| Fehler | Lösung |
+|--------|--------|
+| `Failed to navigate to chrome-extension://...` | Extension nicht installiert oder falsche ID |
+| `Button 'connect' not found` | Extension-Version hat sich geändert, Selektoren aktualisieren (TROUBLESHOOTING_DE.md) |
+| `Failed to extract IP from page` | Alternative IP-Check-Service verwenden (icanhazip.com, ifconfig.me) |
+| `Semaphore closed` | ChromeDriver-Pool zu klein oder zu viele parallele Tasks |
+| `Timeout connecting to server` | Netzwerk-Latenz oder ProtonVPN-Server überlastet, Timeout erhöhen |

+## 🎯 Nächste Schritte
+
+1. **Integration in Economic Module:**
+   ```rust
+   // src/economic/mod.rs
+   use scraper::vpn_integration::VpnIntegration;
+   
+   pub async fn run_full_update_with_vpn(
+       config: &Config,
+       pool: &Arc<ChromeDriverPool>,
+       vpn: &VpnIntegration,
+   ) -> Result<()> {
+       // für jeden Task:
+       if vpn.check_and_rotate_if_needed().await? {
+           sleep(Duration::from_secs(2)).await;
+       }
+       // ... task execution ...
+       vpn.increment_task().await;
+   }
+   ```
+
+2. **Integration in Corporate Module:**
+   - Analog zu Economic
+
+3. **Performance-Tuning:**
+   ```env
+   # Nach Bedarf anpassen:
+   MAX_PARALLEL_TASKS=3      # Start mit 3
+   TASKS_PER_VPN_SESSION=10  # Ballance zwischen IP-Rotation & Performance
+   MAX_TASKS_PER_INSTANCE=0  # 0 = unlimited (einfacher für Anfang)
+   ```
+
+4. **Monitoring:**
+   ```bash
+   # Logs speichern für Analyse
+   RUST_LOG=info cargo run > scraper.log 2>&1
+   
+   # Statistiken beobachten:
+   tail -f scraper.log | grep "Session\|IP\|Connected"
+   ```
+

+
+## 🚨 Wichtige Hinweise
+
+⚠️ **Browser muss für Extension-Automatisierung sichtbar sein**
+- Headless-Mode funktioniert teilweise nicht mit Extension-UI
+- Bei Tests ohne Headless starten für besseres Debugging
+
+⚠️ **ProtonVPN-Account nötig**
+- Kostenlos (Free) reicht aus für diese Integration
+- Free-Tier hat limitierte Server
+
+⚠️ **IP-Rotation nicht garantiert**
+- Load-Balancing auf ProtonVPN-Servern kann zu ähnlichen IPs führen
+- Typischerweise aber unterschiedlich genug für Website-Scraping
+
+⚠️ **Rate-Limiting beachten**
+- VPN ändert nur Browser-Traffic, nicht Rate-Limits der Website
+- Zielwebsite sieht trotzdem parallele Requests von "ähnlicher IP"
+- Lösung: Tasks sequenziell ausführen oder Delays erhöhen
+
+---
+
+## 📞 Support
+
+Für Fragen:
+1. Lesen Sie zuerst **TROUBLESHOOTING_DE.md**
+2. Überprüfen Sie `RUST_LOG=debug cargo run` Output
+3. Nutzen Sie `cargo test` für Unit Tests

+
+## Häufige Probleme
+
+### Problem 1: Extension wird nicht gefunden
+**Symptom:** `Failed to navigate to ProtonVPN extension popup`
+
+**Ursache:** 
+- Extension nicht installiert
+- Falsche Extension-ID in Konfiguration
+- Chrome lädt Extension nicht automatisch
+
+**Lösung:**
+```bash
+# 1. Extension ID überprüfen
+# Chrome öffnen → chrome://extensions/ → ProtonVPN Details anklicken
+# Extension ID kopieren und in .env eintragen
+
+PROTONVPN_EXTENSION_ID=ghmbeldphafepmbegfdlkpapadhbakde  # Aktualisieren!
+
+# 2. Manuell in Chrome installieren
+# https://chrome.google.com/webstore/detail/protonvpn/ghmbeldphafepmbegfdlkpapadhbakde
+```
+
+---
+
+### Problem 2: "Disconnect button not found" oder "Connect button not found"
+**Symptom:** Extension-Buttons werden nicht gefunden
+
+**Ursache:** 
+- Extension UI hat sich geändert (Update)
+- XPath-Selektoren sind veraltet
+- HTML-Struktur unterscheidet sich zwischen Browser-Versionen
+
+**Lösung:**
+```rust
+// 1. Browser DevTools öffnen
+// Chrome: F12 → Öffne chrome-extension://[ID]/popup.html
+
+// 2. HTML inspizieren:
+// Right-click auf Button → Inspect Element
+
+// 3. XPath-Selektoren aktualisieren
+// In src/scraper/protonvpn_extension.rs:
+//
+// Falls neuer HTML-Struktur, z.B.:
+// <button class="vpn-connect-btn">Connect</button>
+//
+// Neuer XPath:
+let xpath = "//button[@class='vpn-connect-btn']";
+
+// Oder alternative Strategien hinzufügen zur find_and_click_button()-Funktion
+```
+
+**Modifizierte find_and_click_button() für neue Selektoren:**
+
+```rust
+async fn find_and_click_button(&self, client: &Client, text: &str) -> Result<()> {
+    let lower_text = text.to_lowercase();
+    
+    let xpath_strategies = vec![
+        // Text-basiert (case-insensitive)
+        format!(
+            "//button[contains(translate(text(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'), '{}')]",
+            lower_text
+        ),
+        // CSS-Klassen (AnpassEN nach Bedarf)
+        format!("//button[contains(@class, '{}')]", text),
+        // Data-Attribute
+        format!("//*[@data-action='{}']", lower_text),
+        // Aria-Label
+        format!("//*[@aria-label='{}']", text),
+        // SVG + Text (für moderne UIs)
+        format!("//*[contains(., '{}')][@role='button']", text),
+    ];
+
+    for xpath in xpath_strategies {
+        if let Ok(element) = client.find(fantoccini::LocatorStrategy::XPath(&xpath)).await {
+            element.click().await?;
+            debug!("Clicked: {}", text);
+            return Ok(());
+        }
+    }
+
+    Err(anyhow!("Button '{}' not found", text))
+}
+```
+
+---
+
+### Problem 3: VPN verbindet sich nicht oder Timeout
+**Symptom:** `Failed to connect to ProtonVPN server 'US' within 15 seconds`
+
+**Ursachen:**
+1. ProtonVPN-Server überlastet
+2. Netzwerk-Latenz
+3. Falsche Server-Name
+4. Browser-Erweiterung nicht vollständig geladen
+
+**Lösungen:**
+
+**A. Timeout erhöhen:**
+```rust
+// In protonvpn_extension.rs, connect_to_server():
+// Erhöhe von 30 auf 60 Versuche
+for attempt in 0..60 {  // 30s → 60 Versuche = 30s timeout
+    sleep(Duration::from_millis(500)).await;
+    if self.is_connected(client).await.unwrap_or(false) {
+        return Ok(());
+    }
+}
+```
+
+**B. Server-Namen überprüfen:**
+```bash
+# Gültige ProtonVPN-Server (für Free-Tier):
+# US, UK, JP, NL, etc.
+# 
+# Oder mit Nummern:
+# US-Free#1, US-Free#2, UK-Free#1
+# US#1, US#2 (für Plus-Tier)
+
+# In .env überprüfen:
+VPN_SERVERS=US,UK,JP,NL
+# NICHT: VPN_SERVERS=US-Free#1, UK-Free#1  (zu viele Leerzeichen)
+```
+
+**C. Extension-Status überprüfen:**
+```rust
+// Debug: Printe HTML vor Connect-Versuch
+let extension_url = format!("chrome-extension://{}/popup.html", self.extension_id);
+client.goto(&extension_url).await?;
+sleep(Duration::from_secs(1)).await;
+
+let html = client.source().await?;
+println!("=== EXTENSION HTML ===");
+println!("{}", html);
+println!("=====================");
+```
+
+---
+
+### Problem 4: IP-Adresse wird nicht extrahiert
+**Symptom:** `Failed to extract IP from whatismyipaddress.com`
+
+**Ursache:** HTML-Struktur hat sich geändert
+
+**Lösung:**
+```rust
+// In protonvpn_extension.rs, get_current_ip():
+// Füge Debug-Ausgabe hinzu:
+
+let page_source = client.source().await?;
+println!("=== PAGE SOURCE ===");
+println!("{}", page_source);
+println!("===================");
+
+// Dann neue Regex/Extraction-Logik basierend auf aktuellem HTML
+```
+
+**Alternative IP-Check-Services:**
+```rust
+// icanhazip.com (gibt nur IP zurück)
+client.goto("https://icanhazip.com/").await?;
+sleep(Duration::from_secs(1)).await;
+let ip = client.source().await?.trim().to_string();
+
+// ifconfig.me
+client.goto("https://ifconfig.me/").await?;
+sleep(Duration::from_secs(1)).await;
+let ip = client.source().await?.trim().to_string();
+
+// checkip.amazonaws.com
+client.goto("https://checkip.amazonaws.com/").await?;
+sleep(Duration::from_secs(1)).await;
+let ip = client.source().await?.trim().to_string();
+```
+
+---
+
+### Problem 5: Session-Manager erstellt Sessions, aber VPN verbindet nicht
+**Symptom:** `VPN session created, but is_connected() returns false`
+
+**Ursache:** 
+- WebDriver-Client hat Extension nicht geladen
+- ChromeDriver-Instanz verwirrt zwischen mehreren Sessions
+
+**Lösung:**
+
+Sicherstellen, dass jeder WebDriver-Client die Extension hat:
+
+```rust
+// In webdriver.rs, ChromeInstance::new() oder new_with_extension():
+// Extension-Pfad muss zu Chrome-Start mitgegeben werden
+
+let mut cmd = Command::new("chromedriver-win64/chromedriver.exe");
+cmd.arg("--port=0");
+
+// Hinweis: Extension wird automatisch geladen, wenn in Chrome installiert
+// Für Testing kann man auch Headless-Modus deaktivieren:
+// cmd.arg("--headless=false");  // Damit man Browser sieht
+```
+
+---
+
+## Konfiguration Debug
+
+### Enable Debug Logging
+```bash
+# Terminal
+RUST_LOG=debug cargo run
+
+# Oder in code:
+tracing_subscriber::fmt()
+    .with_max_level(tracing::Level::DEBUG)  // Statt INFO
+    .init();
+```
+
+### Überprüfen Sie die geladene Konfiguration
+```bash
+# .env Datei überprüfen
+cat .env
+
+# Oder Ausgabe am Start ansehen
+cargo run
+
+# Output sollte zeigen:
+# ✓ Config loaded | VPN: enabled | Max Parallel: 3
+```
+
+### Test-Konfigurationen
+
+**Minimal (ohne VPN):**
+```env
+ENABLE_VPN_ROTATION=false
+MAX_PARALLEL_TASKS=1
+```
+
+**Mit VPN, aber langsam:**
+```env
+ENABLE_VPN_ROTATION=true
+VPN_SERVERS=US,UK
+TASKS_PER_VPN_SESSION=5
+MAX_PARALLEL_TASKS=1  # Nur eine Instanz für Testing
+RUST_LOG=debug
+```
+
+**Mit VPN, normal:**
+```env
+ENABLE_VPN_ROTATION=true
+VPN_SERVERS=US,UK,JP,NL,DE
+TASKS_PER_VPN_SESSION=10
+MAX_PARALLEL_TASKS=3
+```
+
+---
+
+## Extension-Selektoren aktualisieren
+
+### Wie man neue Selektoren findet
+
+1. **Chrome öffnen:**
+   ```
+   chrome://extensions/ → ProtonVPN → Details
+   ```
+
+2. **Popup öffnen:**
+   ```
+   Navigate to: chrome-extension://[ID]/popup.html
+   ```
+
+3. **DevTools öffnen (F12):**
+   - Elements Tab
+   - Inspect Element (Button rechts oben)
+   - Klicke auf Button im Popup
+
+4. **HTML kopieren:**
+   ```html
+   <!-- Beispiel neuer Button -->
+   <button class="btn btn-primary" id="connect-btn">
+       <i class="icon-vpn"></i>
+       Connect
+   </button>
+   ```
+
+5. **Neuen XPath erstellen:**
+   ```rust
+   // Option 1: Nach ID
+   "//button[@id='connect-btn']"
+   
+   // Option 2: Nach Klasse
+   "//button[@class='btn btn-primary']"
+   
+   // Option 3: Nach Text
+   "//button[contains(text(), 'Connect')]"
+   ```
+
+6. **In find_and_click_button() hinzufügen:**
+   ```rust
+   let xpath_strategies = vec![
+       "//button[@id='connect-btn']".to_string(),
+       "//button[@class='btn btn-primary']".to_string(),
+       // ... other strategies
+   ];
+   ```
+
+---
+
+## Performance-Tipps
+
+### 1. Batch-Processing statt paralleles Threading
+```rust
+// ❌ LANGSAM: Zu viele parallele Instances
+let pool = ChromeDriverPool::new(10).await?;
+
+// ✅ SCHNELLER: Weniger Instances, mehr Tasks pro Instance
+let pool = ChromeDriverPool::new(3).await?;
+config.max_tasks_per_instance = 20;  // Recycel nach 20 Tasks
+```
+
+### 2. VPN-Verbindung optimieren
+```rust
+// ❌ LANGSAM: Jeder Task rotiert IP
+TASKS_PER_VPN_SESSION=1
+
+// ✅ SCHNELLER: Mehrere Tasks pro IP
+TASKS_PER_VPN_SESSION=10
+```
+
+### 3. Timing anpassen
+```rust
+// Zu aggressive:
+sleep(Duration::from_millis(100)).await;
+
+// Besser (für VPN):
+sleep(Duration::from_millis(500)).await;
+
+// Für Disconnect/Connect Sequenzen:
+// Mindestens 2-3 Sekunden zwischen Operationen
+```
+
+### 4. Server-Auswahl
+```env
+# ❌ Problematic: Zu viele ähnliche Server
+VPN_SERVERS=US-Free#1,US-Free#2,US-Free#3,US-Free#4
+
+# ✅ Better: Mix aus verschiedenen Ländern
+VPN_SERVERS=US-Free#1,UK-Free#1,JP-Free#1,NL-Free#1
+```
+
+---
+
+## Testing ohne VPN
+
+### 1. VPN deaktivieren für Testing
+```env
+ENABLE_VPN_ROTATION=false
+MAX_PARALLEL_TASKS=1
+ECONOMIC_LOOKAHEAD_MONTHS=1  # Kleinere Datenmenge
+```
+
+### 2. Mock-Tests schreiben
+```rust
+#[tokio::test]
+async fn test_vpn_session_manager() {
+    let mgr = VpnSessionManager::new(
+        vec!["US".to_string(), "UK".to_string()],
+        3
+    );
+    
+    mgr.create_new_session().await.unwrap();
+    assert!(mgr.get_current_session().await.is_some());
+}
+```
+
+### 3. Extension-Fehler isolieren
+```bash
+# Test nur extension.rs
+cargo test --lib scraper::protonvpn_extension
+```
+
+### 4. Scraping ohne VPN testen
+```bash
+# Setze ENABLE_VPN_ROTATION=false
+ENABLE_VPN_ROTATION=false RUST_LOG=info cargo run
+```

+# OpenFIGI API Summary: Mapping, Search, and Filter Endpoints
+
+This Markdown summary covers the **API Guidelines**, **Request Format**, and **Sample Request -> Sample Response** for the key OpenFIGI endpoints: Mapping, Search, and Filter. Information is based on the official documentation as of December 1, 2025.
+
+## Mapping Endpoint
+
+### API Guidelines
+- **Endpoint**: `POST /v3/mapping`
+- **Purpose**: Map third-party identifiers (e.g., ISIN, TICKER) to FIGIs (Financial Instrument Global Identifiers).
+- **Request Format**: JSON array of objects (mapping jobs). Each job requires `idType` and `idValue`. Optional filters: `exchCode`, `micCode`, `currency`, `marketSecDes`, `securityType`, `securityType2`, `includeUnlistedEquities`, `optionType`, `strike`, `contractSize`, `coupon`, `expiration`, `maturity`, `stateCode`.
+- **Key Parameters**:
+  - `idType` (String, Required): Identifier type (e.g., `ID_BB_GLOBAL`, `TICKER`, `ID_ISIN`).
+  - `idValue` (String/Number, Required): The identifier value.
+  - `exchCode` (String, Optional): Exchange code (mutually exclusive with `micCode`).
+  - `micCode` (String, Optional): Market Identification Code (mutually exclusive with `exchCode`).
+  - Range parameters (e.g., `strike`, `expiration`): Arrays like `[a, b]` or `[a, null]` for intervals.
+  - `includeUnlistedEquities` (Boolean, Optional): Defaults to `false`.
+- **Limits**:
+  - Without API key: Max 5 jobs per request.
+  - With API key: Max 100 jobs per request.
+- **Rate Limits**:
+  - Without API key: 25 requests/minute.
+  - With API key: 25 requests/6 seconds.
+- **Authentication**: Include `X-OPENFIGI-APIKEY` header for higher limits.
+
+### Sample Request

+## Search Endpoint
+
+### API Guidelines
+- **Endpoint**: `POST /v3/search`
+- **Purpose**: Keyword-based search for FIGIs with optional filters; supports pagination.
+- **Request Format**: JSON object with optional `query` (keywords) and filters (same as Mapping). Use `start` for pagination.
+- **Key Parameters**:
+  - `query` (String, Optional): Search keywords (e.g., "ibm").
+  - `start` (String, Optional): Pagination token from previous `next` field.
+  - All Mapping filters supported (e.g., `exchCode`, `securityType`, `optionType`).
+- **Limits**:
+  - Max results: 15,000.
+  - Max per page: 100.
+  - Max pages: 150.
+- **Rate Limits**:
+  - Without API key: 5 requests/minute.
+  - With API key: 20 requests/minute.
+- **Pagination**: Response includes `next` token; use as `start` in next request.
+- **Authentication**: Same as Mapping.
+
+### Sample Request
+```json
+{
+    "query": "ibm",
+    "exchCode": "US"
+}
+```
+
+### Sample Response
+```json

+
+## Filter Endpoint
+
+### API Guidelines
+- **Endpoint**: `POST /v3/filter`
+- **Purpose**: Filter-based search for FIGIs (no keywords required); results sorted alphabetically by FIGI, includes total count.
+- **Request Format**: JSON object with optional `query` and filters (same as Search/Mapping). Use `start` for pagination.
+- **Key Parameters**: Identical to Search (`query`, `start`, and all Mapping filters).
+- **Limits**: Same as Search (15,000 max results, 100/page, 150 pages).
+- **Rate Limits**: Same as Search (5/min without key, 20/min with key).
+- **Pagination**: Same as Search; response includes `total` count.
+- **Authentication**: Same as Mapping.
