npx hardhat to initialize the smart contract

npx hardhat compile to compile the Greeter.sol and create the smart contract

We will use abi(application binary interface) inside of src/artifacts/contracts/Greeter.sol/Greeter.json We are going to be importing this to our frontend app to interact with the smart contract

npx hardhat node to run a local test network to deploy this smart contract inside our local blockchain, it will give us 20 accounts to work with

npx hardhat run scripts/deploy.js --network localhost is going to deploy smart contract to the local test network. It will give the address of the deployed smart contract at the end

You need to install metamask as an extension to the browser

Connect to localhost 8545 instead of Ethereum Mainnet

Import the first test account that is created by running npx hardhat node

As a result you will see (10.00 ETH - smart contract gas fee) amount of Tets Ethereum in your metamask
