+# SvelteKit Prototype
+
+A new SvelteKit-based prototype of the BlockPy application has been created in the `sveltekit-prototype/` directory.
+
+## What is this?
+
+This prototype demonstrates what BlockPy could look like if rebuilt with modern web technologies, specifically SvelteKit and Svelte 5. It showcases the potential benefits of using a modern reactive framework for the BlockPy interface.
+
+## Quick Start
+
+```bash
+cd sveltekit-prototype
+npm run dev
+```
+
+Visit `http://localhost:5173` to see the prototype in action.
+
+## Documentation
+
+See the full documentation in [sveltekit-prototype/README.md](sveltekit-prototype/README.md)
+
+## Key Features
+
+- ✨ Modern component-based architecture
+- 🎨 Clean, responsive design
+- ⚡ Fast development with Hot Module Replacement
+- 📦 Significantly smaller bundle size (~50KB vs ~1.4MB)
+- 🔧 Easy to maintain and extend
+
+## Screenshots

+
+## Note
+
+This is a **prototype** focusing on UI/UX demonstration. It does not include the full BlockPy functionality (Blockly, Skulpt, server integration, etc.). It's meant to showcase the potential architecture and benefits of using SvelteKit.

+# BlockPy SvelteKit Prototype
+
+This is a prototype demonstration of what BlockPy could look like built with SvelteKit.
+
+## Overview
+
+This prototype showcases a modern reimagining of the BlockPy interface using SvelteKit, a modern web framework built on Svelte. It demonstrates the core UI structure and layout of BlockPy without the full functionality (which would require Blockly, Skulpt, and other dependencies).
+
+## Features Demonstrated
+
+- **Modern UI Framework**: Built with SvelteKit 2.x and Svelte 5
+- **Responsive Design**: Works on desktop and mobile devices
+- **Editor Modes**: Toggle between Python, Blocks, and Split view (UI only)
+- **Component Architecture**: Modular components for easy maintenance
+- **Clean Styling**: Modern CSS with CSS variables for theming
+
+## Components
+
+- `Toolbar.svelte` - Action buttons and mode selection
+- `EditorPanel.svelte` - Code/blocks editor area
+- `FeedbackPanel.svelte` - Feedback display
+- `ConsolePanel.svelte` - Console output display
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js 18+ and npm
+
+### Installation
+
+Dependencies are already installed. If you need to reinstall:
+
+```bash
+npm install
+```
+
+### Development
+
+Run the development server:
+
+```bash
+npm run dev
+```
+
+Open your browser to `http://localhost:5173`
+
+### Building
+
+Create a production build:
+
+```bash
+npm run build
+```
+
+Preview the production build:
+
+```bash
+npm run preview
+```
+

+
+## What This Prototype Shows
+
+✅ **UI Structure**: The layout and organization of BlockPy's interface  
+✅ **Component Design**: How different parts of the UI can be organized as components  
+✅ **Modern Framework**: Benefits of using SvelteKit (routing, SSR, etc.)  
+✅ **Responsive Layout**: Mobile-friendly design  
+✅ **State Management**: Reactive state using Svelte's built-in reactivity
+
+## What This Prototype Doesn't Include
+
+❌ **Code Execution**: No Skulpt integration (Python execution)  
+❌ **Block Editor**: No Blockly integration (visual blocks)  
+❌ **Advanced Features**: No server communication, state persistence, etc.  
+❌ **Full Dependencies**: Doesn't include the full BlockPy ecosystem
+
+## Next Steps for Full Implementation
+
+To turn this prototype into a full BlockPy application:
+
+1. **Integrate Blockly**: Add Blockly library for visual block editing
+2. **Integrate Skulpt**: Add Skulpt for Python code execution
+3. **Add BlockMirror**: Integrate block-to-text conversion
+4. **Server Integration**: Add API calls for saving/loading assignments
+5. **State Management**: Implement comprehensive state management
+6. **Testing**: Add unit and integration tests
+7. **Accessibility**: Enhance accessibility features
+8. **Performance**: Optimize for large codebases
+
+## Technology Stack
+
+- **SvelteKit**: Full-stack framework for building web applications
+- **Svelte 5**: Component framework with excellent reactivity
+- **Vite**: Fast build tool and dev server
+- **CSS Variables**: For easy theming
+
+## Benefits of SvelteKit
+
+- **Modern Development Experience**: Fast HMR, great DX
+- **Better Performance**: Smaller bundle sizes, faster runtime
+- **Built-in Routing**: File-based routing out of the box
+- **SSR/SSG Support**: Server-side rendering and static site generation
+- **TypeScript Support**: First-class TypeScript support
+- **Modern JavaScript**: Uses latest JavaScript features
+
+## Comparison with Current BlockPy
+
+| Feature | Current BlockPy | SvelteKit Prototype |
+|---------|----------------|-------------------|
+| Framework | Webpack + KnockoutJS | SvelteKit + Svelte 5 |
+| Bundle Size | ~1.4MB | ~50KB (base) |
+| Reactivity | Observable-based | Compiler-based |
+| Build Tool | Webpack 4 | Vite |
+| Development | Slower rebuilds | Fast HMR |
+| Learning Curve | Steeper | Gentler |
+
+## License
+
+Same as BlockPy main project.
