+2. They pick a **destination** (`farm`, `map`, `powergrid`, `workshop`, `general`, `environment`)
+3. They select a folder containing:
    - `model.glb` or `model.gltf` (required)
    - Textures: `roughness`, `normal`, `metalness`, `color`, `displace` (`.png/.jpg/.webp`, optional)
-3. The model is displayed in a 3D preview
-4. On clicking "Upload & Push to GitHub", each file is sent to the `/api/upload` endpoint
-5. For models: the file is written to `/tmp`, compressed with Blender Draco, then the compressed version is pushed to GitHub
-6. For textures: pushed directly to GitHub without compression
-7. If Blender is unavailable, the original model is pushed as-is (graceful fallback)
+4. The model is displayed in a 3D preview
+5. On clicking "Envoyer sur GitHub":
+   - The app checks if the folder already exists on the remote repo
+   - If it exists, a confirmation dialog is shown listing the existing files that will be replaced
+   - On confirmation (or if the folder is new), all files are sent to the `/api/upload` endpoint
+6. For models: the file is written to `/tmp`, compressed with Blender Draco, then the compressed version is pushed
+7. For textures: pushed directly without compression
+8. All files are pushed in a **single commit** with a formatted message:
+   ```
+   update: upload-gltf add a new model -> farm/my-model
+
+   📦 Model
+     ✅ model.gltf (compressed)
+   🎨 Textures
+     ✅ color.jpg
+     ❌ metalness (manquant)
+   ```
+9. If the folder already existed, orphan files (present in the old version but not in the new upload) are deleted in the same commit
+10. If Blender is unavailable, the original model is pushed as-is (graceful fallback)
+
+## Destinations
+
+Uploaded models are pushed to `public/models/<destination>/<folderName>/` in the target repo:
+
+| Destination | Path |
+|-------------|------|
+| Farm | `public/models/farm/` |
+| Map | `public/models/map/` |
