I have VPN experience although I think with Windscribe Pro you should just need to install the software and then select which server region you would like to VPN in to?
I use Private Internet Access. All I had to do was install the software (on Macs and iOS devices) and type in my user ID and password. I haven`t had any problem with it other than one issue: when the software is active, I can`t make and receive calls on my MacBook Pro.
I`m a Mac consultant and technician. If you need Mac help, I`ll be glad to assist you.
