-
- **WebGL-basierte Rendering-Engine** für hohe Performance
- **Dynamische Knoten und Verbindungen** mit realistischem Bewegungsverhalten
- **Neuronenfeuer-Simulation** mit Signalweiterleitung zwischen Knoten

-
-## Content Security Policy (CSP)
-
-Die Anwendung implementiert eine Content Security Policy, um die Sicherheit zu erhöhen und unerwünschte externe Ressourcen zu blockieren. CSP wird in `app.py` konfiguriert und schränkt ein, welche Ressourcen geladen werden dürfen.
-
-### Aktualisierung (06.06.2024)
-Die Anwendung verwendet nun die Tailwind CSS CDN für vereinfachte Entwicklung. Die CSP wurde entsprechend angepasst, um die Domain `cdn.tailwindcss.com` zu erlauben.
-
-### Lokale und CDN-Ressourcen
-
-Die Anwendung nutzt eine Mischung aus lokalen Ressourcen und CDNs:
- **CDN-Ressourcen**: 
-  - Tailwind CSS (cdn.tailwindcss.com)
- **Lokale Ressourcen**:
-  - Alpine.js
-  - Font Awesome
-  - Google Fonts (Inter und JetBrains Mono)
-  - WebGL-Animation (neural-network-background.js)
-
-### CSP-Nonces
-
-Die Anwendung verwendet Nonces für Inline-Skripte. In den Templates wird `{{ csp_nonce }}` verwendet, um den Nonce-Wert einzufügen:
-
-```html
-<script nonce="{{ csp_nonce }}">
-  // JavaScript Code
-</script>
+```
+python setup.py
 ```

-*Zuletzt aktualisiert: 15.06.2024* 
+Dies erstellt eine virtuelle Umgebung, installiert alle Abhängigkeiten und erstellt die CSS-Dateien mit Tailwind.
+
+### Manuelle Installation
+
+1. Repository klonen:
+   ```
+   git clone <repository-url>
+   ```
+
+2. Python-Abhängigkeiten installieren:
+   ```
+   cd website
+   pip install -r requirements.txt
+   ```
+
+3. Environment-Variablen konfigurieren:
+   ```
+   cp example.env .env
+   ```
+   Bearbeite die `.env`-Datei und füge deinen OpenAI API-Schlüssel ein.
+
+4. CSS mit Tailwind erstellen:
+   ```
+   python build_css.py
+   ```
+
+5. Datenbank initialisieren:
+   ```
+   python init_db.py
+   ```
+
+6. Anwendung starten:
+   ```
+   python run.py
+   ```
+
+## Entwicklung
+
+Für die Entwicklung mit automatischem CSS-Reload:
+
+```
+python dev.py
+```
+
+Dieser Befehl startet sowohl den Flask-Server als auch den Tailwind CSS-Watcher, der CSS bei Änderungen automatisch neu generiert.
+
+## Verwendung des KI-Assistenten
+
+Der KI-Assistent ist über folgende Wege zugänglich:
+
+1. **Schwebende Schaltfläche**: In der unteren rechten Ecke der Webseite ist eine Roboter-Schaltfläche, die den Assistenten öffnet.
+2. **Navigation**: In der Hauptnavigation gibt es ebenfalls eine Schaltfläche mit Roboter-Symbol.
