+## Memory Bank Project by [@GreatScottyMac](https://github.com/GreatScottyMac)
+
+The [Roo Code Memory Bank](https://github.com/GreatScottyMac/roo-code-memory-bank) project solves a critical challenge in AI-assisted development: **maintaining context across sessions**. By providing a structured memory system integrated with VS Code, it ensures your AI assistant maintains a deep understanding of your project across sessions.
+
+**Key Features**
+
+- 🧠 **Persistent Context**: Remembers project details across sessions and maintains consistent understanding of your codebase
+- 🔄 **Smart Workflows**: Mode-based operation with automatic context switching and project-specific customization
+- 📊 **Knowledge Management**: Structured documentation with technical decision tracking and automated progress monitoring
+
+Check out the [Memory Bank project on GitHub](https://github.com/GreatScottyMac/roo-code-memory-bank) to get started!
