Getting ready

It's expected that you have a basic understanding of the Ethereum blockchain and solidity before stepping through this recipe.

The Remix IDE (https://remix.ethereum.org) can help you quickly test and deploy the contract. Also, you can use any Ethereum client (geth, parity, and so on) and the solc compiler to run this contract.
