+renew_nomad_certificates_consul_user: nomad # by default, set to nomad

+renew_nomad_certificates_vault_addr: https://vault.example.com # by default, set to https://vault.example.com
 ```
 This variable defines the address the consul-template service will query to get the new certificates. Defaults to localhost, but can be changed if vault isnt reachable on localhost.
 
 ```yaml
-renew_vault_certificates_vault_token: mysupersecretvaulttokenthatyoushouldchange # by default, set to a dummy string
+renew_nomad_certificates_vault_token: mysupersecretvaulttokenthatyoushouldchange # by default, set to a dummy string

 ```yaml
-renew_vault_certificates_vault_token_unwrap: false # by default, set to false

 ```yaml
-renew_vault_certificates_vault_token_renew: true # by default, set to true
+renew_nomad_certificates_vault_token_renew: true # by default, set to true
 ```
 This variable defines whether or not to renew the vault token. It should probably be `true`, and you should have a periodic token to handle this.
