+## 🚀 STL Storage Application - Repository Creation
+
+This repository contains a complete STL file storage and 3D viewer application that needs to be pushed to https://teapot.hm.keyb.ie
+
+### 📋 Manual Repository Creation Steps
+
+Since "push to create" is not enabled on the Gitea server, please follow these steps:
+
+1. **Navigate to Gitea Web Interface:**
+   - Go to https://teapot.hm.keyb.ie
+   - Log in as user `kris`
+
+2. **Create New Repository:**
+   - Click "+" or "New Repository" button
+   - Repository name: `stl-storage`
+   - Description: `Web-based STL file storage and 3D viewer application`
+   - Visibility: Public (recommended) or Private
+   - **DO NOT** initialize with README, .gitignore, or license (we have these already)
+
+3. **Push Local Repository:**
+   ```bash
+   cd /home/kris/testing
+   git push -u origin main
+   ```
