+# Atomaste - Guide de Déploiement
+
+## Architecture
+
+```
+c:\Users\antoi\WEBtomaste\     <-- SOURCE (Master)
+         |
+         | deploy-hostinger.bat
+         v
+   atomaste.ca                  <-- PRODUCTION (Hostinger)
+```
+
+**Workflow:** Tu modifies les fichiers localement, puis tu déploies sur Hostinger.
+
+---
+
+## Fichiers du site
+
+| Fichier | Description |
+|---------|-------------|
+| `index.html` | Page d'accueil (anglais) |
+| `fr.html` | Page d'accueil (français) |
+| `.htaccess` | Configuration serveur Apache |
+| `Media/` | Images et logos |
+
+### Fichiers Media utilisés:
+- `Atomaste_logo_A.svg` - Favicon
+- `Atomaste_light_grey_Logo.svg` - Logo header/footer
+- `Site_1_8.png` - Photo Antoine
+
+---
+
+## Déploiement
+
+### Option 1: Script automatique (recommandé)
+
+Double-clique sur:
+```
+deploy-hostinger.bat
+```
+
+Ce script upload automatiquement tous les fichiers nécessaires.
+
+### Option 2: Commandes manuelles (curl)
+
+```bash
+# Upload un fichier spécifique
+curl -u "u878837096:hey@claudeLeta12" -T "index.html" "ftp://145.223.77.209/domains/atomaste.ca/public_html/"
+
+# Upload une image
+curl -u "u878837096:hey@claudeLeta12" -T "Media/MonImage.png" "ftp://145.223.77.209/domains/atomaste.ca/public_html/Media/"
+```
+
+### Option 3: Demander à Claude
+
+Dis simplement: "deploy to hostinger" ou "push to production"
+
+---
+
+## Accès FTP Hostinger
+
+| Paramètre | Valeur |
+|-----------|--------|
+| Host | `ftp://145.223.77.209` |
+| Username | `u878837096` |
+| Password | `hey@claudeLeta12` |
+| Port | `21` |
+| Remote Path | `/domains/atomaste.ca/public_html` |
+
+**Note:** Ces credentials sont aussi dans `deploy-hostinger.bat` et `deploy-hostinger.ps1`
+
+---
+
+## Structure sur le serveur Hostinger
+
+```
+/domains/atomaste.ca/public_html/
+├── index.html
+├── fr.html
+├── .htaccess
+└── Media/
+    ├── Atomaste_logo_A.svg
+    ├── Atomaste_light_grey_Logo.svg
+    └── Site_1_8.png
+```
+
+---
+
+## Ajouter une nouvelle image
+
+1. Place l'image dans `Media/` localement
+2. Référence-la dans ton HTML: `<img src="Media/nom-image.png">`
+3. Upload avec:
+   ```bash
+   curl -u "u878837096:hey@claudeLeta12" -T "Media/nom-image.png" "ftp://145.223.77.209/domains/atomaste.ca/public_html/Media/"
+   ```
+4. Ou ajoute la ligne dans `deploy-hostinger.bat`
+
+---
+
+## Troubleshooting
+
+### Le site ne se met pas à jour
+- Fais un hard refresh: `Ctrl+Shift+R`
+- Ouvre en navigation privée
+- Vérifie que l'upload a réussi (pas de "FAILED")
+
+### Erreur 550 (File unavailable)
+- Le dossier n'existe pas sur le serveur
+- Utilise `--ftp-create-dirs` avec curl
+
+### L'ancien site WordPress apparaît
+- Le `.htaccess` a été écrasé par WordPress
+- Re-upload le `.htaccess` local
+
+---
+
+## URLs
+
+- **Production:** https://atomaste.ca
+- **Français:** https://atomaste.ca/fr.html
+- **LinkedIn:** https://www.linkedin.com/company/atomaste/
+
+---
+
+## Serveur de développement local (optionnel)
+
+Tu as aussi un serveur dev sur Dalidou:
+```
+deploy-to-dalidou.bat  -->  http://192.168.86.50:8090
+```
