+# Normogen
+
+## Overview
+
+Normogen is a privacy-focused health data tracking and management platform. The name comes from Mapudungun, relating to "Balanced Life."
+
+## Vision
+
+To record as many variables related to health as possible, store them in a secure, private manner, to be used by **you**, not by corporations. From medication reminders to pattern analysis, Normogen puts you in control of your health data.
+
+## Key Features
+
+### Core Functionality
+- 🔐 **Zero-knowledge encryption** - Your data is encrypted before it reaches the server
+- 👥 **Multi-person profiles** - Track health data for yourself, children, elderly family members
+- 👨‍👩‍👧‍👦 **Family structure** - Manage family health records in one place
+- 🔗 **Secure sharing** - Share specific data via expiring links with embedded passwords
+- 📱 **Mobile apps** - iOS and Android with health sensor integration
+- 🌐 **Web interface** - Access from any device
+
+### Health Data Tracking
+- Lab results storage
+- Medication tracking (dosage, schedules, composition)
+- Health statistics (weight, height, trends)
+- Medical appointments
+- Regular checkups
+- Period tracking
+- Pregnancy tracking
+- Dental information
+- Illness records
+- Phone sensor data (steps, activity, sleep, blood pressure, temperature)
+
+## Architecture
+
+### Technology Stack
+- **Backend API**: Rust
+- **Web Server**: Node.js
+- **Database**: MongoDB (with zero-knowledge encryption)
+- **Frontend**: Web + iOS + Android
+- **Deployment**: Docker on Linux
+
+### Security Model
+- **Client-side encryption**: Data encrypted before leaving the device
+- **Zero-knowledge**: Server stores only encrypted data
+- **Proton-style encryption**: AES-256-GCM with PBKDF2 key derivation
+- **Shareable links**: Self-contained decryption keys in URLs
+- **Privacy-first**: No data selling, subscription-based revenue
+
+## Documentation
+
+- [Introduction](./introduction.md) - Project vision and detailed feature specification
+- [Encryption Implementation Guide](./encryption.md) - Zero-knowledge encryption architecture
+- [Research](./thoughts/research/) - Technical research and planning documents
+
+## Development Status
+
+🚧 **Current Phase**: Planning/Documentation
+
+### Completed
+- ✅ Project vision and requirements
+- ✅ Security architecture design
+- ✅ Encryption implementation guide
+- ✅ Feature specifications
+- ✅ Git repository initialization
+
+### Next Steps
+- [ ] Select Rust framework (Actix, Axum, Rocket?)
+- [ ] Design database schema
+- [ ] Implement authentication system
+- [ ] Build CRUD API
+- [ ] Create web frontend
+- [ ] Add encryption layer
+- [ ] Implement sharing functionality
+
+## Open Source
+
+Normogen is open-source. Both server and client code will be publicly available.
+
+## License
+
+TBD
+
+## Contributing
+
+TBD - While in planning phase, contributions are welcome through discussion and documentation improvements.
