 If installing from source, Git is required. You can install Git using the `geerlingguy.git` role.
 
+Generally, installing from source (see section `Source Installation from Git`) leads to a better experience using Certbot and Let's Encrypt, especially if you're using an older OS release.

The defaults run `certbot renew` (or `certbot-auto renew`) via cron every day at 03:30:00 by the user you use in your Ansible playbook. It's preferred that you set a custom user/hour/minute so the renewal is during a low-traffic period and done by a non-root user account.

+### Wildcard Certificates
+
+Let's Encrypt supports [generating wildcard certificates](https://community.letsencrypt.org/t/acme-v2-and-wildcard-certificate-support-is-live/55579), but the process for generating and using them is slightly more involved. See comments in [this pull request](https://github.com/geerlingguy/ansible-role-certbot/pull/60#issuecomment-423919284) for an example of how to use this role to maintain wildcard certs.
