Vesta Let's Encrypt SSL again - what is the up-to-date way?

[pivey]

I was reading trough almost all form posts & 3rd party websites, how to secure VestaCP with SSL,
..and i almost got crazy :) Most of them have different approach.
Which of all of them is the correct up-to-date way to secure the panel?
Is it not enough to setup Let's Encrypt support on default domain, created on setup?

In one of the threads it's mentioned "Now there is a new way that is built-in Vesta"

What's the build in procedure?

Every chicken finds a piece of corn :)
I solved installing my SSL for Vesta, Exim and dovecot daemons by

a) enabled SSL with Letsencrypt support for my hostname domain in Vesta Panel
b) followed these instructions viewtopic.php?p=72237#p72237 by starting at step 2
