Improving Indentation and adding Comments in codebase

## Problem
There are few indentation issues and the code lacks the comments that would help it be easier to read.

## Description
Adding suitable comments in the codebase and maintaining-proper indentation throughout

## Additional context
Comment serve as a reminder to change something in the future. Code commenting also becomes invaluable when you want to ‘comment out’ code. This is when you turn a block of code into a comment because you don’t want that code to be run, but you still want to keep it on hand in case you want to re-add it.

## Implementation
- [x] I would be interested in implementing this feature.
