 define the correct env variables above in your .env file and you should now have a working OVH Object Storage setup :)
 
 # Usage

-In addition, the [large object support](https://www.ovh.com/us/g1951.optimised_method_uploading_files_object_storage) in OVH has also been implemented. Note that the large object support only works for stream resources (the object obtained from `fopen` for example).
+`Storage::url()`
+
+and
+
+`Storage::temporaryUrl()`
+
+The temporary url is relevant for private containers where files are not publicly accessible under normal conditions. This generates a temporary url with expiry (see details [here](https://github.com/laravel/framework/pull/20375) for usage).
+
+Note that this requires the container to have a proper header. The key in the header should match the `urlKey` specified in `filesystems.php`. For details on how to setup the header on your OVH container, see [here](https://www.ovh.com/us/g2007.share_object_via_temporary_url#generate_your_temporary_url).

 - the SwiftAdapter was created by Nimbusoft (https://github.com/nimbusoftltd/flysystem-openstack-swift) and I have just modified it to provide the url function
 - cyberx86 did the hard work of figuring out how to get the Openstack setup going with OVH (https://www.thatsgeeky.com/2016/08/openstack-php-and-ovh/)
 - rackspace for maintaining the Openstack repo (https://github.com/php-opencloud/openstack)
