This project was created using create-react-app and the sample project from hardhat. I deployed the contract to the Ropsten Testnet with an Infura node via the provided endpoint.
In the project directory, you can run:
npm run start
Ensure you have the Metamask extension installed, switch over to the Ropsten testnet and have some testnet ETH to be able to change the greeting.
