-📕 Read the docs: https://docs.soliditylang.org
+> 🔥 We'll use **burner wallets** on localhost...
 
-📚 Go through each topic from [solidity by example](https://solidity-by-example.org) editing `YourContract.sol` in **🏗 scaffold-eth**
+> 👛 Explore how **burner wallets** work in 🏗 scaffold-eth by opening a new *incognito* window and navigate it to http://localhost:3000. You'll notice it has a new wallet address in the top right. Copy the incognito browsers' address and send localhost test funds to it from your first browser:

+> 👨🏻‍🚒 When you close the incognito window, the account is gone forever. Burner wallets are great for local development but you'll move to more permanent wallets when you interact with public networks.
