-It is possible to store LFS objects to a remote object storage which allows you
-to offload R/W operation on local hard disk and freed up disk space significantly.
-You can check which object storage can be integrated with GitLab [here](http://fog.io/about/provider_documentation.html)
-(Since GitLab is tightly integrated with `Fog`, you can refer the documentation)
-You can also use an object storage in a private local network. For example,
