A few months ago I installed a SSL certificate with Letsencrypt. I didn’t make much notes, trusting that when I would need to renew, I could find instructions on the Letsencrypt website.
However, when I look now on the Letsencrypt website I see instructions for an application called Certbot that I don’t have, while there is nothing for Letsencrypt application (I have a Letsencrypt subdirectory) that I have.
How should I proceed?
