[Docs]: Write the README.md file

[sanskriti2005]

Proposed Changes (Tasks):

• An introduction with an objective (on top)
• Contribution guidelines
• A description of the tech-stack used
• A detailed description of the future scope
• Acknowledgements to the contributors
• A section for the demo and prototype
• A table of contents section to easily access any section of the README.md file

Additional Context:
My idea if how the flow of things will be:
The introduction with the name and objective -> The how to start the website (made by sristy) -> Description of tech-stack -> Future scope -> Contribution guidelines
