directory structure CI4

So the index.php in CI4 has been moved to public. For development its not that great a big deal to set up virtual hosts in /etc/httpd/httpd.conf and tweak /etc/hosts

However on hosting its not uncommon to have several directories in your hosting account and basically when domain points to a directory say nextbigthing  then when somebody puts url nextbigthing.org  it points to directory nextbigthing and server is looking for some index.html or in a php framework a bootstrap index.php

So the only thing i can think of if i upload CI4.zip to my server  for a project is   to use some form of re-direct from Cpanel so that a live url  for nextbigthing.org actually will get pointed to the public dir of codeigniter dir structure of project.

Is that the way it is envisaged things  will be done or maybe use a  .htaccess in  root of web project ?

CMS CI4     I use Arch Linux by the way
