How to - PIA through OpenVPN with some LAN traffic bypassing VPN

[cobrahead]

I am starting with a fresh install of Pfsense and I have an account with PIA. What is the best tutorial for setting up PIA with OpenVPN and allowing some traffic on my local network to bypass the VPN and use my ISP? I know there are several tutorials out there. Which is the best/most up to date? I would like to use the strongest encryption possible with PIA as well.

For the machines using PIA I wish to have no DNS leak and also have the internet cutout if the VPN goes down.

Thanks
