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

+ * 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
+ *
+ * You'll also need a mnemonic - the twelve word phrase the wallet uses to generate
+ * public/private key pairs. If you're publishing your code to GitHub make sure you load this
+ * phrase from a file you've .gitignored so it doesn't accidentally become public.
