 2   * Use this file to configure your truffle project. It's seeded with some
 3   * common settings for different networks and features like migrations,
 4   * compilation and testing. Uncomment the ones you need or modify
 5   * them to suit your project as necessary.
 6   *
 7   * More information about configuration can be found at:

 9   * truffleframework.com/docs/advanced/configuration
10   *
11   * To deploy via Infura you'll need a wallet provider (like truffle-hdwallet-provider)
12   * to sign your transactions before they're sent to a remote public node. Infura accounts
13   * are available for free at: infura.io/register.
14   *
15   * You'll also need a mnemonic - the twelve word phrase the wallet uses to generate
16   * public/private key pairs. If you're publishing your code to GitHub make sure you load this
17   * phrase from a file you've .gitignored so it doesn't accidentally become public.
