Open a Node.js console:
> const ZWeb3 Contracts SimpleProject => // Initialize a web3 provider.> ZWeb3> // Load the contract.> const MyContract = Contracts> // Instantiate a project.> myProject = 'MyProject' from: await ZWeb3> // Create a proxy for the contract.> myProject> // Make a change on the contract, and compile it.> const MyContractUpgraded = Contracts> myProject
