+```bash
+# Install PostgreSQL in Termux
+pkg install postgresql
+
+# Start PostgreSQL
+initdb ~/postgres
+pg_ctl -D ~/postgres -l logfile start
+
+# Create database
+createdb giglez
+
+# Run schema
+psql giglez < scripts/schema.sql
+```
+
+### 2. Create Schema Script (Day 1)
+Extract SQL from docs/database_schema.md into executable script.
+
+### 3. T-Embed Testing (Day 2-3)
+- Flash Bruce firmware
+- Test serial communication
+- Verify JSON protocol
+- Capture test signals
+
+### 4. GPS Integration (Day 3-4)
+- Install SL4A in Android
+- Test GPS acquisition
+- Stream coordinates to Termux
+- Log GPS data
+
+### 5. First Capture (Day 5)
+- Integrate all components
+- Capture real signal with GPS
+- Store in database
+- Verify data integrity
+
+## Known Challenges
+
+### Technical
+1. **Battery Life**: Continuous GPS + RF scanning drains battery quickly
+   - Solution: Implement duty cycling, power management
+2. **Serial Reliability**: USB serial can disconnect on Android
+   - Solution: Auto-reconnect logic, connection monitoring
+3. **Database Size**: Raw captures can grow large quickly
+   - Solution: Compression, selective storage, archival strategy
+
+### Hardware
+1. **CC1101 Frequency Gaps**: Can't cover entire spectrum
+   - 300-348, 387-464, 779-928 MHz only
+2. **Antenna Tuning**: Different frequencies need different antennas
+   - Solution: Multi-band antenna or frequency-specific sessions
+
+### Community
+1. **Verification Quality**: User-submitted IDs may be incorrect
+   - Solution: Multi-voter verification, reputation system
+2. **Privacy**: GPS coordinates could reveal home locations
+   - Solution: Anonymization options, GPS precision controls
+
+## Resources Needed
+
+### Development
+- [ ] Termux on Android with USB OTG support
+- [ ] LilyGo T-Embed CC1101 device
+- [ ] SD card (16GB+) for T-Embed
+- [ ] Multi-band sub-GHz antenna
+
+### Testing
+- [ ] Known devices for validation (garage remote, car key fob, etc.)
+- [ ] RTL-SDR for signal verification (optional)
+
+## Success Metrics
