To automatically renew, set up a cron job like so:
```shell
# Enable the crond service
doas rc-update add crond
doas rc-service crond start
# Test that renewals work
doas certbot renew --cert-name yourinstance.tld --nginx --dry-run
# Add the renewal task to cron

If that doesnt work, make sure, that nginx is not already running. If it still doesnt work, try setting up nginx first (change ssl “on” to “off” and try again). Often the answer to issues with certbot is to use the `--nginx` flag once you have nginx up and running.
If you are using any additional subdomains, such as for a media proxy, you can re-run the same command with the subdomain in question. When it comes time to renew later, you will not need to run multiple times for each domain, one renew will handle it.

If you are using certbot, it is HIGHLY recommend you set up a cron job that renews your certificate, and that you install the suggested `certbot-nginx` plugin. If you don't do these things, you only have yourself to blame when your instance breaks suddenly because you forgot about it.
First, ensure that the command you will be installing into your crontab works.
