How to setup Let's Encrypt for Nginx on Ubuntu 16.04 (including IPv6, HTTP/2 and A+ SLL rating)

There are two main modes to run the Let's Encrypt client (called Certbot):

Standalone: replaces the webserver to respond to ACME challenges
Webroot: needs your webserver to serve challenges from a known folder.

Webroot is better because it doesn't need to replace Nginx (to bind to port 80).

In the following, we're setting up mydomain.com. HTML is served from /var/www/mydomain, and challenges are served from /var/www/letsencrypt.

This let's me git clone a template repo, cd into and fire up a new template in my editor of choice:

$ clone starter # clones https://github.com/addyosmani/starter (a personal boilerplate)

$ clone h5bp html5-boilerplate # get me HTML5 Boilerplate

$ clone angular angular-seed # same for AngularJS seed

$ clone polymerlabs seed-element # same for a new Polymer element
