Hosted version here: https://swaraj-postmessage-demo.netlify.app

Steps to run locally:

1. Clone the repository.
2. You can directly open the index.html file in your prefered browser OR if you use VSCode, you can use an extension called Live Server to open the index.html file and it'll take care of hot-reloading for you (you won't have to reload manually every time you make changes 😉)
