 Next, we have to delete the `Counter.sol` file in the `src` folder and create another file called `NFT.sol`. You can do this by running:
 
 ```sh
-rm src/Counter.sol test/Counter.t.sol && touch src/NFT.sol && ls src
+rm src/Counter.sol test/Counter.t.sol script/Counter.s.sol && touch src/NFT.sol && ls src
 ```
