+# SSL Certificates Management
+
+This directory contains tools for managing SSL certificates for all Mnemo Cards domains.
+
+## Domains and Certificates
+
+The following domains require SSL certificates:
+
+| Domain | Purpose | Certificate Path |
+|--------|---------|------------------|
+| `mnemo-cards.online` | Main web application | `/etc/letsencrypt/live/mnemo-cards.online/` |
+| `api.mnemo-cards.online` | Backend API | `/etc/letsencrypt/live/api.mnemo-cards.online/` |
+| `admin.mnemo-cards.online` | Admin panel | `/etc/letsencrypt/live/admin.mnemo-cards.online/` |
+| `code.mnemo-cards.online` | Forgejo Git server | `/etc/letsencrypt/live/code.mnemo-cards.online/` |
+| `vscode.mnemo-cards.online` | VSCode Server | `/etc/letsencrypt/live/vscode.mnemo-cards.online/` |
+
+## Certificate Issuance
+
+Certificates are automatically obtained during deployment:
+
+- **Main site**: `tools/deploy/web-app/deploy.sh`
+- **Admin panel**: `tools/deploy/admin/deploy.sh`
+- **API**: Handled by backend deployment
+- **Forgejo/VSCode**: Handled by their respective deployments
+
+## Tools
+
+### Check Certificate Status
+```bash
+./check_ssl.sh
+```
+
+### Setup All Certificates
+Obtain SSL certificates for all domains automatically:
+```bash
+sudo ./setup_ssl.sh
+```
+This script will:
+- Stop nginx temporarily
+- Obtain certificates for all domains using Let's Encrypt
+- Restart nginx
+- Configure automatic renewal via cron
+
+### Obtain Certificate Manually
+```bash
+# Stop nginx temporarily
+sudo systemctl stop nginx
+
+# Get certificate
+sudo certbot certonly --standalone -d DOMAIN_NAME --email admin@mnemo-cards.online --agree-tos
+
+# Start nginx again
+sudo systemctl start nginx
+```
+
+### Renew Certificates
+```bash
+sudo certbot renew
+```
+
+### Force Renewal
+```bash
+sudo certbot renew --force-renewal
+```
+
+## Certificate Validation
+
+The CI/CD pipeline automatically checks SSL certificates during deployment:
+
+- Certificate validity (must not expire within 30 days)
+- HTTPS accessibility for all domains
+- Certificate renewal configuration
+
+## Troubleshooting
+
+### Certificate Not Found
+- Run the deployment script for the specific service
+- Check that the domain DNS points to the server
+- Verify nginx configuration
+
+### Certificate Expired
+- Run `sudo certbot renew`
+- Check cron jobs for automatic renewal
+- Verify Let's Encrypt account status
+
+### HTTPS Not Working
+- Check nginx configuration syntax: `sudo nginx -t`
+- Verify certificate files exist and are readable
+- Check firewall settings: `sudo ufw status`
+
+## Cron Jobs
+
+Automatic certificate renewal is configured via cron:
+
+```bash
+# Check existing cron jobs
+crontab -l
+
+# Example renewal jobs (configured automatically)
+0 12 * * * /usr/bin/certbot renew --quiet --cert-name mnemo-cards.online
+0 12 * * * /usr/bin/certbot renew --quiet --cert-name api.mnemo-cards.online
+0 12 * * * /usr/bin/certbot renew --quiet --cert-name admin.mnemo-cards.online
+```
+
+## Security Notes
+
+- All certificates use Let's Encrypt (preferred) with self-signed fallbacks
+- Admin panel uses enhanced security headers
+- Rate limiting is enabled for admin endpoints
+- Certificates are automatically renewed before expiration
