+
+## 🛠️ Getting Started
+
+### Prerequisites
+- [Node.js](https://nodejs.org/) (v18+)
+- [pnpm](https://pnpm.io/) (recommended)
+
+### Installation
+```bash
+npm install
+```
+
+### Development
+Start the interactive showcase:
+```bash
+npm run dev
+```
+
+### Testing
+Run the comprehensive test suite (Vitest + Happy DOM):
+```bash
+npm test
+```
+
+### Building
+Build all examples as a unified Multi-Page Application (MPA):
+```bash
+npm run build
+```
+
+## ✨ Recent Improvements
+- **Performance:** Implemented dynamic imports for heavy dependencies (A-Frame, Three.js) to optimize load times and test execution.
+- **Instance Reuse:** Refactored complex components (Force Graph, Draggable DOM) to reuse instances and prevent memory leaks.
+- **UI/UX:** Overhauled `lit-html-table` with modern accessibility-focused styling and improved `lit-draggable-dom` coordinate mapping for perfect panning.
+- **Consistency:** Unified all subprojects into a single Vite-powered monorepo structure with shared testing and build configurations.
