Untill Symfony is not yet released you should use this:

composer create-project symfony/skeleton testt --stability=beta

After release just remove --stability statement.
Symfony is no longer support symfony installer.

Is there a best practise how to deploy a S4 project in a virtual machine? a VM deploy isn't a 12 factor app, so I'm not sure how how to set env variables without dotEnv.
