This section gets your MetaMask wallet set up to start interacting with Creaticles. If you already have a MetaMask wallet, you can skip the section on Wallet Setup. The next section, Getting Started on Testnet, helps you: 1) configure MetaMask to connect to Ropsten Test Network, which is the network that Creaticles lives on in testnet, and 2) get some testnet ETH, which is used to interact on Creaticles by paying gas fees and giving testnet rewards for winners of proposals.
