Example of simplest possible config?

[Raven21]

Sorry if this is an answered question.

I set up a Raspberry Pi 3B+ with a couple NAS drives, transmission, and OpenVPN. I want to ensure that OpenVPN is always running on it, and I read that it should be pretty reliable. My problem is that all the examples of configs are based on a server/client relationship, and probably have a lot of functionality I don't need. Can anyone tell me what the simplest possible config I can use should look like? I literally just want it to contain my credentials so that the Pi itself is using the VPN. I don't need anything else on the VPN.

I apologize if I sound like a fool.

Thanks.
