Fix Documentations

[rudrajit1729]

There is a constant need of a HERO who can fix documentations. Here is your chance to be the savior. Fix Documentations, elaborate if you can, make the document interesting to read and easy to comprehend.

Not restricted by any bucket. Wherever there is a need for better documentation, there is a need for your fix.

Restrict from SPAMMING PRs by fixing a minor spell check or making unnecessary edits. Fixing a typo is required but SPAMMING is not.

You don't need to be assigned to fix README files, if you can better it we welcome your PR.
