+# 📚 LaTeX to MDX Integration
+
+Cette intégration permet de convertir automatiquement des sources LaTeX en MDX pour Astro, avec surveillance en temps réel des changements.
+
+## 🚀 Utilisation
+
+### Mode Développement avec LaTeX Watch
+
+```bash
+# Démarre le serveur de développement avec surveillance LaTeX
+npm run dev:with-latex
+```
+
+Cette commande :
+1. ✅ Convertit initialement LaTeX → MDX
+2. 🔄 Surveille `scripts/latex-to-mdx/input/` pour les changements
+3. 🌐 Lance le serveur Astro sur http://localhost:4321
+4. 📝 Régénère automatiquement `article.mdx` lors de modifications
+
+### Mode Production
+
+```bash
+# Build de production (convertit LaTeX puis build Astro)
+npm run build
+```
+
+### Scripts Individuels
+
+```bash
+# Conversion unique LaTeX → MDX
+npm run latex:convert
+
+# Surveillance LaTeX uniquement
+npm run latex:watch
+
+# Développement Astro classique (sans LaTeX)
+npm run dev
+```
+
+## 📁 Structure LaTeX
+
+Place tes sources LaTeX dans :
+```
+app/scripts/latex-to-mdx/input/
+├── main.tex              # Document principal
+├── main.bib              # Bibliographie  
+├── sections/             # Chapitres/sections
+│   ├── 01_introduction.tex
+│   ├── 02_methods.tex
+│   └── ...
+├── figures/              # Images
+└── ...                   # Autres fichiers LaTeX
+```
+
+## ⚙️ Fonctionnalités
+
+- 🔄 **Conversion automatique** : 2 secondes par conversion
+- 📊 **Surveillance complète** : Tout le dossier `input/`
+- 🎯 **Intégration Docker** : Pandoc installé automatiquement
+- 🌐 **Hot reload** : Astro recharge automatiquement après conversion
+- 📝 **Logs colorés** : Différenciation LaTeX/Astro dans la console
+
+## 🐳 Docker
+
+Le Dockerfile inclut maintenant :
+- Installation automatique de Pandoc
+- Conversion LaTeX → MDX avant le build Astro
+- Support complet de l'environnement LaTeX
+
+## 🛠️ Debugging
+
+Si la conversion échoue :
+1. Vérifier les logs LaTeX (en bleu)
+2. Vérifier que Pandoc est installé
+3. Tester la conversion manuelle : `npm run latex:convert`
