Remove Public from URL

I use also MAMP, I actually point my docroot to add an additional folder public, so that all non-public folder and files are outside docroot and all in one folder structure.

For shared hosting, yes we should use some little configuration, to make it work as it should, like mentioned in this thread: https://forum.codeigniter.com/thread-76777.html

But for subdomain or add-on domain as a shared user in cpanel or directadmin or any modern panel, actually we can use additional folder to point the docroot, just like in MAMP.
