I want better documentation for our project.

Things you add:

1. Add the steps to run the code locally.
2. Add some details about the frameworks used.
3. Add Screenshots of the web pages, for a clear understanding of the project.
4. Add the contributor guidelines.
5. Add the steps to make a pr for a newbie contributor.
6. Add some memes/gifs to make a more attractive readme. (show your creativity)
