+   sudo ./setup-systemd.sh
+   ```
+
+2. **Install Monitoring:**
+   ```bash
+   cd ~/guru-connect/infrastructure
+   sudo ./setup-monitoring.sh
+   ```
+
+3. **Configure Automated Backups:**
+   ```bash
+   sudo cp ~/guru-connect/server/guruconnect-backup.* /etc/systemd/system/
+   sudo systemctl daemon-reload
+   sudo systemctl enable guruconnect-backup.timer
+   sudo systemctl start guruconnect-backup.timer
+   ```
+
+4. **Install Log Rotation:**
+   ```bash
+   sudo cp ~/guru-connect/server/guruconnect.logrotate /etc/logrotate.d/guruconnect
+   ```
+
+### Optional Testing
+
+1. **Test Manual Backup:** (Requires PostgreSQL credentials fix)
+   ```bash
+   cd ~/guru-connect/server
+   ./backup-postgres.sh
+   ```
+
+2. **Test Health Monitor:**
+   ```bash
+   cd ~/guru-connect/server
+   ./health-monitor.sh
+   ```
+
+3. **Configure Cron for Health Checks:** (If not using Prometheus alerting)
+   ```bash
+   crontab -e
+   # Add: */5 * * * * /home/guru/guru-connect/server/health-monitor.sh
+   ```
+
+### Phase 1 Week 3 (Next)
+
+Continue with CI/CD automation:
+- Gitea CI pipeline configuration
+- Automated builds on commit
+- Automated tests in CI
+- Deployment automation scripts
+- Build artifact storage
+- Version tagging automation
+
+---
+
+## Known Issues
+
+### 1. PostgreSQL Credentials
+
+**Issue:** Database password authentication still failing
+**Impact:** Cannot test backup/restore end-to-end
+**Status:** Known blocker from Week 1
+**Workaround:** Server runs in memory-only mode
+
+**Note:** Backup scripts are ready and will work once credentials are fixed.
+
+### 2. Systemd Installation
+
+**Requirement:** Sudo access needed for systemd service installation
+**Status:** Scripts ready, awaiting installation
+**Workaround:** Server runs via `nohup` currently
