+# World Generation Realist Module
+
+**Responsabilité**: Génération procédurale géologiquement réaliste avec architecture Phase/Step.
+
+## Description
+
+Ce module définit les interfaces pour un système de génération procédurale basé sur une architecture Phase/Step modulaire. Conçu pour implémenter le système 8-phases défini dans `gameData/WorldGeneration/Regular_world.json`.
+
+## Architecture
+
+### Interfaces Core
+- **IWorldGenerationPhase**: Interface pour les phases de génération (ex: Geological, Climate, Budget, Resource)
+- **IWorldGenerationStep**: Interface pour les étapes individuelles au sein d'une phase
+
+### Conception
+- **Phase**: Groupe logique d'étapes (ex: Phase Géologique = Cratères + Tectonique + Volcans + Érosion)
+- **Step**: Opération atomique de génération avec dépendances explicites
+- **Modularité**: Chaque phase/step isolé et testable
+- **Progress tracking**: Suivi granulaire de progression
+
+## Contraintes Modules
+- **200-300 lignes max** par implémentation
+- **JSON-only communication** via IDataNode
+- **Autonomous builds**: `cd src/modules/world-generation-realist/ && cmake .`
+- **Hot-reload compatible**: State serialization requise
+
+## Build System
+
+### Commands
+```bash
+cd src/modules/world-generation-realist/
+cmake .                                    # Configuration autonome
+# Note: Aucune library créée tant qu'il n'y a pas d'implémentations
+```
+
+### Dependencies
+- `nlohmann/json`: Configuration JSON processing
+- `IDataNode`: Interface configuration depuis core/
+- `C++20`: Features modernes
+
+### Structure Prévue
+```
+include/
+├── IWorldGenerationPhase.h       # Interface phase
+├── IWorldGenerationStep.h        # Interface step
+└── (futures implémentations...)
+```
+
+---
+
+**État actuel**: Interfaces définies, prêt pour implémentations concrètes.
