A lot of unnecessary things have been added like in setup.md,the documents are meant for easy navigation through the project.This looses the essence of the core changes required.
Kindly avoid making any unnecessary changes outside the realm of the needful.
Also,I am seeing everyone out there is making some common and repetitive mistakes.

Kindly revisit and confine all the changes strictly inside the realm of the issue.
