title: Difference between certbot and certbot-auto
body: <p>I am using <code>letsencrypt</code> for my server to support https. When looking around I find commands with <code>certbot</code> and others with <code>certbot-auto</code> with similar funcionalities. Do you need to use consistently one or the other? Can someone expalin the difference and in which case you would use each one? </p>
