New Install

Hello,

I am new to Code Igniter. I'm developing a Content Management System. My question, is there a way to do a custom configuration.php file so that I don't have to share the ENV files or anything to make it easier for users to update their Database credentials? Also -- i'd like to build a custom index.php that goes into the app. I'm going to be using Ioncube to encrypt my files, so I want to make it rather easy to accomplish all this. The script I'll be using for Licensing actually is found here.

I'm new to the MVC type framework. Any guidance would be well appreciated!

Thank you
