Update Readme

[Raporaz03]

I can update your documentation adding more instructions for beginners and adding some gifs and images so that it will be more attractive.

Tell me what you want from contributors as it is not clear so how and what they can contribute.

Now you can contribute. Please write with a brief description and it should be beginner friendly. Happy Hacking!!
