+## Configuration Variables
+
+All variables below can be set at either the account level (`~/.getssl/getssl.cfg`) or the per-domain level (`~/.getssl/<domain>/getssl.cfg`). Settings at the domain level override those at the account level.

+| `DNS_WAIT` | `5` | Seconds between DNS propagation re-checks |
+| `DNS_WAIT_COUNT` | `100` | Maximum number of DNS propagation re-checks before giving up |
+| `DNS_WAIT_RETRY_ADD` | `"false"` | Re-run `DNS_ADD_COMMAND` every 10 retries if DNS hasn't updated |
+| `DOMAIN_CERT_LOCATION` | `""` | Destination for the domain certificate file |
+| `DOMAIN_CHAIN_LOCATION` | `""` | Destination for a combined domain + CA certificate file |
+| `DOMAIN_KEY_CERT_LOCATION` | `""` | Destination for a combined private key + domain certificate file |
