The case is really simple get started!

For starters requirements:
Nginx 1.13.0

  listen [::]:443 ssl http2;

  server_name example.com;
  root /var/www/example.com/public;

  ssl_certificate /path/to/your/certificate.crt;
  ssl_certificate_key /path/to/your/private.key;

  ssl_protocols TLSv1.2 TLSv1.3;
