Let's encrypt client is now called certbot

[heygrady]

Your docs recommend installing the old let's encrypt client -- which is probably wrong.

Your docs are great but they are drifting out of date. In May of 2016, the EFF superseded the letsencrypt cleint with certbot.

Digital Ocean has a similar docs to yours. They demonstrate using certbot

# see the digital ocean docs for details
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install certbot
sudo certbot certonly --webroot --webroot-path=/var/www/html -d example.com -d www.example.com
