Let's Encrypt certificate in a shared hosting Godaddy server?

I saw the site, and here’s what I understood: 1- connect to my server using ssh.
2- install acme in the server.
3 -issue a cert
4-Install issued cert to apache/nginx etc. /* I have Apache so ? */
The end?
P.s: what about these lines :
The installer will perform 3 actions:
Create and copy acme.sh to your home dir ($HOME): ~/.acme.sh/. All certs will be placed in this folder.
Create alias for: acme.sh=~/.acme.sh/acme.sh.
Create everyday cron job to check and renew the cert if needed.
