 The information from Radarr will not be added to $_ENV as one might expect but should be included in the [$_SERVER variable](https://secure.php.net/manual/en/reserved.variables.server.php).

+Symlinking is preferable over hardlinking in most cases as the root movie folder can be on a seperate drive or nfs mount, where hardlinks are impossible.
