IMPORTANT NOTES:

- Congratulations! Your certificate and chain have been saved at:
  /etc/letsencrypt/live/ejemplo.com/fullchain.pem
  Your key file has been saved at:
  /etc/letsencrypt/live/ejemplo.com/privkey.pem
  Your cert will expire on 2019-07-03. To obtain a new or tweaked
  version of this certificate in the future, simply run certbot again
  with the "certonly" option. To non-interactively renew *all* of
  your certificates, run "certbot renew"
- Your account credentials have been saved in your Certbot
  configuration directory at /etc/letsencrypt. You should make a
  secure backup of this folder now. This configuration directory will
  also contain certificates and private keys obtained by Certbot so
  making regular backups of this folder is ideal.
