Update README file

[ANSHIKA1806]

@ArunTeltia
README is the first file one should read when starting a new project. It's a set of useful information about a project, and a kind of manual. A README text file appears in many various places and refers not only to programming. So i want to make your README file more meaningful and more easier to understand the whole project.
