Let's Encrypt w/ VPS

Since this isn’t UMate specific - I figured I’d ask here - I heard Wimpy talking about it on LUP…

I’m currently using Arvixe as my VPS host (it gives me 6 domains for $67 / 2 years)… and I want to use let’s encrypt on them… but I’m not seeing how… Their support is less than helpful, so I thought I’d turn to my favorite community to see what I could learn…

It’s using CPanel, but doesn’t have the Let’s Encrypt plugin installed, and I don’t have root access (although I have SSH access of course)…

Anyone out there using a similar VPS who got Let’s Encrypt installed???
