Creating ovpn File

I was so happy to see that in the latest version of FreshTomato that the ability to generate VPN keys was added. I now have a working VPN that allows me to connect two of my routers in two different countries. I would now like to create an ovpn file to allow me to import each of the router’s VPN settings to other devices but I don’t know how. Can anyone guide me to a location where there are examples or instructions on how to create the ovpn file using my routers VPN settings?
Thanks
