 This command will install the newest compatible Circom compiler, compile the provided circuit, download the necessary `ptau` file regarding the number of circuit's constraints, build the required `zkey` and `vkey` files, and generate TypeScript object wrappers to enable full typization of signals and ZK proofs.
 
-Afterward, you may run the provided hardhat script via `npx hardhat run ./scripts/multiplier.test.ts`.
+Afterward, copy the provided script to the `test` directory and run the tests via `npx hardhat test`. You will see that all the tests are passing!
