IMPORTANT NOTES: - Congratulations! Your certificate and chain have been saved at

 /etc/letsencrypt/live/www.sl-informatique.ovh/fullchain.pem. Your
 cert will expire on 2017-06-06. To obtain a new or tweaked version
 of this certificate in the future, simply run certbot again. To
 non-interactively renew *all* of your certificates, run "certbot
 renew"

- If you lose your account credentials, you can recover through

 e-mails sent to sebastien@sl-informatique.fr.

- 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.
