+
+## Endpoints API
+
+### Benchmarks
+- `POST /api/benchmark` - Soumettre un benchmark (auth required)
+- `GET /api/benchmarks/{id}` - Détails d'un benchmark
+
+### Devices
+- `GET /api/devices` - Liste des devices (pagination + recherche)
+- `GET /api/devices/{id}` - Détails d'un device
+- `GET /api/devices/{id}/benchmarks` - Historique benchmarks
+- `PUT /api/devices/{id}` - Modifier un device
+
+### Links
+- `GET /api/devices/{id}/links` - Liens d'un device
+- `POST /api/devices/{id}/links` - Ajouter un lien
+- `PUT /api/links/{id}` - Modifier un lien
+- `DELETE /api/links/{id}` - Supprimer un lien
+
+### Documents
+- `GET /api/devices/{id}/docs` - Documents d'un device
+- `POST /api/devices/{id}/docs` - Upload document
+- `GET /api/docs/{id}/download` - Télécharger document
+- `DELETE /api/docs/{id}` - Supprimer document
+
+### Autres
+- `GET /api/health` - Health check
+- `GET /api/stats` - Statistiques globales
+
+## Documentation interactive
+
+Une fois le serveur lancé, accédez à :
+- Swagger UI : http://localhost:8007/docs
+- ReDoc : http://localhost:8007/redoc
+
+## Variables d'environnement
+
+| Variable | Description | Défaut |
+|----------|-------------|--------|
+| `API_TOKEN` | Token d'authentification | `CHANGE_ME` |
+| `DATABASE_URL` | URL de la base SQLite | `sqlite:///./backend/data/data.db` |
+| `UPLOAD_DIR` | Répertoire des uploads | `./uploads` |
+| `CORS_ORIGINS` | Origins CORS autorisées | `["*"]` |
+
+## Authentification
+
+L'API utilise un token Bearer simple pour l'endpoint POST /api/benchmark :
+
+```http
+Authorization: Bearer YOUR_API_TOKEN
+```
+
+## Base de données
+
+SQLite avec 5 tables principales :
+- `devices` - Machines
+- `hardware_snapshots` - Snapshots hardware
+- `benchmarks` - Résultats de benchmarks
+- `manufacturer_links` - Liens constructeurs
+- `documents` - Documents uploadés
+
+## Développement
