-## Certificate Management
-
-The server uses standard systemd restart for certificate updates. Restart time is less than 1 second.
-
-### Let's Encrypt Integration
-
-For automatic certificate renewal with certbot:
-
-```bash
-# Create post-renewal hook
-sudo tee /etc/letsencrypt/renewal-hooks/post/restart-pollux.sh > /dev/null << 'EOF'
-#!/bin/bash
-# Restart Pollux after Let's Encrypt certificate renewal
-
-systemctl restart pollux
-logger -t certbot-pollux-restart "Restarted pollux after certificate renewal"
-EOF
-
-# Make it executable
-sudo chmod +x /etc/letsencrypt/renewal-hooks/post/restart-pollux.sh
-
-# Test the hook
-sudo /etc/letsencrypt/renewal-hooks/post/restart-pollux.sh
-```
-
-### Manual Certificate Update
-
-```bash
-# Restart server to load new certificates
-sudo systemctl restart pollux
-
-# Check restart in logs
-sudo journalctl -u pollux -f
-```
