+## 🤖 Built with Claude Code
+
+GhostPaste is a testament to the power of AI-assisted development. This entire project was built through a collaborative dialogue between human creativity and Claude's technical expertise. From architecture decisions to implementation details, every line of code emerged from thoughtful conversation.
+
+### The Collaboration Story
+
+What started as an idea for a privacy-focused code sharing platform evolved through hundreds of interactions with Claude Code. Together, we:
+
+- **Architected** a zero-knowledge encryption system that keeps data private
+- **Designed** a clean, intuitive UI using modern React patterns
+- **Implemented** edge-compatible code for global performance
+- **Solved** complex challenges like versioning and binary encoding
+- **Refined** the user experience through iterative improvements
+
+This project demonstrates that AI can be more than just a coding assistant - it can be a true development partner that helps bring ideas to life while maintaining high standards for security, performance, and user experience.
+
+### Key Achievements
+
+- **100% AI-Paired Development**: Every component built through human-AI collaboration
+- **Production-Ready Code**: Comprehensive testing, error handling, and documentation
+- **Security-First Design**: Encryption implementation guided by best practices
+- **Modern Architecture**: Leveraging cutting-edge web technologies
