+## Deployment
+
+### Development (Run directly from Git repo)
+
+```bash
+cd TrulyMEM-TrueHumanMEM
+python3 trulymem_entry.py --web --port 4096
+```
+
+### Production (Systemd + standalone directory)
+
+```bash
+# Copy code to standalone deployment directory
+cp -r TrulyMEM-TrueHumanMEM /home/trulymem
+
+# Create Systemd service
+cat > /etc/systemd/system/trulymem-web.service << 'EOF'
+[Unit]
+Description=TrulyMEM - True Human Memory (Web Mode)
+After=network.target
+
+[Service]
+Type=simple
+User=root
+WorkingDirectory=/home/trulymem
+ExecStart=/usr/bin/python3 /home/trulymem/trulymem_entry.py --web --port 4096
+Restart=always
+RestartSec=5
+StandardOutput=journal
+StandardError=journal
+
+[Install]
+WantedBy=multi-user.target

+
+systemctl daemon-reload
+systemctl enable trulymem-web.service
+systemctl start trulymem-web.service
+
+# Check status
+systemctl status trulymem-web.service
+```
+
+> **Note**: Do not run the service directly from the Git repository to avoid polluting it with runtime artifacts (logs, databases, etc.).
+
+### Web Access
+
+The service runs at `http://localhost:4096`. On first visit, you'll need to set up an admin account and log in.
+
+### Updating Deployment
+
+```bash
+cd TrulyMEM-TrueHumanMEM
+git pull
+cp -r * /home/trulymem/
+systemctl restart trulymem-web.service
+```
