 ### Gather the needed details
 
-For this tutorial, we're going to connect to a smart contract called `Greeter` that's included with a new [Hardhat](https://hardhat.io) project. It's been deployed to the Ropsten testnet at the address `0xE0282e76237B8eB19A5D08e1741b8b3e2691Dadd`, and you can find details about it on the [EtherScan Ropsten block explorer](https://ropsten.etherscan.io) by searching for that address, which should take you to [the address detail view](https://ropsten.etherscan.io/address/0xE0282e76237B8eB19A5D08e1741b8b3e2691Dadd).
