Want to improve README.md

[kkkkkabir]

The README.md is a bit low on what the course is all about. I guess telling a bit about object-oriented programming in the start itself will give newbies a heads up on what they are diving into.

Can we add: Object Oriented Programming helps us to keep data and the functions which will handle the data together. We need to keep in mind a class keeps related information together, unrelated information needs to be in a separate class. For example: User and Product needs to be separate classes though a User instance may call functions of a Product instance.

Hello,

We need to add introduction to Object Oriented Programming as well as an Index linking different examples.
