I wrote up my own HOWTO for nginx just the other day.<a href="https:&#x2F;&#x2F;www.uhoreg.ca&#x2F;blog&#x2F;20160218-1757" rel="nofollow">https:&#x2F;&#x2F;www.uhoreg.ca&#x2F;blog&#x2F;20160218-1757</a>  I used the acme-tiny client instead of the official client.  My post is mostly aimed at Debian-based distributions, but should be easily adaptable to others.
