Documentation needs to be updated

[shamim-42]

I was going through the codebase, it's a well organized project.
By the way, maybe the documentation (Readme of main branch) is not updated according to the new changes. I am seeing there is a folder core inside the lib folder which is a sibling of data folder, but there is no written details in the documentation about this core folder.
I would request the owner to update the documentation.
Thanks!

@zubairehman any update on the documentation? I'd like to use it, but I'm struggling to understand where to start with the new organization. As shamim said, the several identical folders seem to be spread across the code base.
