+
+- Obtain a new certificate via webroot authorization, but do not install it automatically:
+
+`sudo certbot certonly --webroot --webroot-path {{path/to/webroot}} --domain {{subdomain.example.com}}`
+
+- Obtain a new certificate via nginx authorization, installing the new certificate automatically:
+
+`sudo certbot --nginx --domain {{subdomain.example.com}}`
+
+- Obtain a new certificate via apache authorization, installing the new certificate automatically:
+
+`sudo certbot --apache --domain {{subdomain.example.com}}`
+
+- Renew all Let's Encrypt certificates that expire in 30 days or less (don't forget to restart any servers that use them afterwards):
+
+`sudo certbot renew`
+
+- Simulate the obtaining of a new certificate, but don't actually save any new certificates to disk:
+
+`sudo certbot --webroot --webroot-path {{path/to/webroot}} --domain {{subdomain.example.com}} --dry-run`
+

+
+`sudo certbot --webroot --webroot-path {{path/to/webroot}} --domain {{subdomain.example.com}} --test-cert`
