 This role requires variables defined in [defaults/main.yml](defaults/main.yml). Feel free to overwrite them as needed for your HashiCorp Vault setup for example in a `group_vars` or `host_vars` file.
 
-* `fqdn_reverse`: A variable that contains the reversed fully qualified domain name for each host. For `fully.qualified.domain.name` this variable will equal `name.domain.qualified.fully`. Consider this a suggestion for how to set up your HashiCorp Vault `kv` secrets hierarchy.
+* `fqdn_reverse`: A variable that contains the reversed fully qualified domain name for each host with each dot (`.`) replaced by a slash (`/`). For `fully.qualified.domain.name` this variable will equal `name/domain/qualified/fully`. Consider this a suggestion for how to set up your HashiCorp Vault `kv` secrets hierarchy.
 
 * `local_os_password_vault_vars`: The variables you want extracted from your Vault instance, by default `['password', 'password_salt']` which contain the new password to set for the local account and a salt, respectively.
