 ## Comment l'utiliser ?
 
-### Installation locale
+### Déploiement en Production
 
-1. Clonez le dépôt.
-2. Installez les dépendances avec `pnpm install`.
-3. Configurez les variables d'environnement (voir `.env.example`).
-4. Lancez les services via Docker ou manuellement.
+Le projet est prêt pour la production via Docker Compose.
+
+1. **Prérequis** : Docker et Docker Compose installés.
+2. **Variables d'environnement** : Copiez `.env.example` en `.env.prod` et ajustez les valeurs (clés secrètes, hosts, Sentry DSN, etc.).
+3. **Lancement** :
+   ```bash
+   docker-compose -f docker-compose.prod.yml up -d
+   ```
+4. **Services inclus** :
+   - **Frontend** : Next.js en mode standalone optimisé.
+   - **Backend** : NestJS avec clustering et monitoring Sentry.
+   - **Caddy** : Gestion automatique du SSL/TLS.
+   - **ClamAV** : Scan antivirus en temps réel des médias.
+   - **Redis** : Cache, sessions et limitation de débit (Throttling/Bot detection).
+   - **MinIO** : Stockage compatible S3.
+
+### Sécurité et Performance
+- **Transcodage Auto** : Toutes les images sont converties en WebP et les vidéos en WebM pour minimiser la bande passante.
+- **Bot Detection** : Système intégré de détection et de bannissement automatique des crawlers malveillants via Redis.
+- **Monitoring** : Tracking d'erreurs et profilage de performance via Sentry (Node.js et Next.js).
