/**
 * Use this file to configure your truffle project. It's seeded with some

 * compilation and testing. Uncomment the ones you need or modify
 * them to suit your project as necessary.
 *
 * More information about configuration can be found at:
 *
 * truffleframework.com/docs/advanced/configuration
 *
 * To deploy via Infura you'll need a wallet provider (like truffle-hdwallet-provider)
 * to sign your transactions before they're sent to a remote public node. Infura API
 * keys are available for free at: infura.io/register
