SSH with the -F option returns me usage

Question

I want to create a config file and tell ssh to deal with it. I don't want to use ~/.ssh/config because these are config files per project and not per user. So I'm trying to roll with:

ssh -F project_servers.ssh

And terminal returns ssh usage. This is the contents of the file I want SSH to play with:

Host preview
User xxxx
Port 52
HostName xxxx.com

Anybody knows what I'm doing wrong here?

Thanks

You still need to request the named Host section on the command line:

ssh -F project_servers.ssh preview
