+# La Vida Luca - FastAPI Backend
+
+API backend pour la plateforme La Vida Luca - Formation des jeunes en MFR, développement d'une agriculture nouvelle et insertion sociale.
+
+## Fonctionnalités
+
+### Sécurité et Middleware
+- ✅ Gestion d'erreurs centralisée
+- ✅ Configuration CORS
+- ✅ Middleware de sécurité (TrustedHost)
+- ✅ Rate limiting
+- ✅ Authentification JWT
+- ✅ Validation des tokens
+
+### API Endpoints
+- ✅ Authentification (register, login, refresh token)
+- ✅ Gestion des activités
+- ✅ Protection par JWT
+- ✅ Documentation automatique (Swagger/OpenAPI)
+
+### Base de données
+- ✅ Modèles SQLAlchemy optimisés
+- ✅ Configuration Alembic pour les migrations
+- ✅ Pooling de connexions
+- ✅ Support PostgreSQL avec asyncpg
+
+### Tests
+- ✅ Configuration pytest
+- ✅ Tests unitaires (auth, middleware)
+- ✅ Tests d'intégration (API endpoints)
+- ✅ Couverture de code configurée
+
+## Installation
+
+1. Installer les dépendances:
+```bash
+pip install -r requirements.txt
+```
+
+2. Configurer les variables d'environnement:
+```bash
+cp .env.example .env
+# Éditer .env avec vos paramètres
+```
+
+3. Initialiser la base de données:
+```bash
+alembic init
+alembic revision --autogenerate -m "Initial migration"
+alembic upgrade head
+```
+
+## Utilisation
+
+### Développement
+```bash
+python main.py
+```
+
+### Production
+```bash
+uvicorn main:app --host 0.0.0.0 --port 8000
+```
+
+### Tests
+```bash
+# Tests unitaires
+pytest tests/test_auth.py -v
+
+# Tests d'intégration
+pytest tests/test_integration.py -v
+
+# Tous les tests avec couverture
+pytest --cov=app
+```
+
+## Documentation API
+
+Une fois l'application lancée:
+- Swagger UI: http://localhost:8000/docs
+- ReDoc: http://localhost:8000/redoc
+
+## Configuration
+
+Voir `.env.example` pour les variables d'environnement disponibles:
+- Configuration de base de données
+- Clés de sécurité JWT
+- Paramètres CORS
+- Limites de taux
+
