 To enable SSL, see [nginx.conf](nginx.conf) and uncomment the lines:
 ```
 listen 443 ssl;
 ssl_certificate     /opt/certs/example.com.crt;
 ssl_certificate_key /opt/certs/example.com.key;

-This will enable HTTPS using a self-signed certificate supplied in [/certs](/certs). If you wish to use HTTPS, it is **highly recommended** to obtain your own certificates and update the `ssl_certificate` and `ssl_certificate_key` paths.
