+ * Use this file to configure your truffle project. It's seeded with some
+ * common settings for different networks and features like migrations,
+ * 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:
+ *
+ * https://trufflesuite.com/docs/truffle/reference/configuration
+ *
+ * Hands-off deployment with Infura
+ * --------------------------------
+ *
+ * Do you have a complex application that requires lots of transactions to deploy?
+ * Use this approach to make deployment a breeze 🏖️:
+ *
+ * Infura deployment needs a wallet provider (like @truffle/hdwallet-provider)
+ * to sign transactions before they're sent to a remote public node.
+ * Infura accounts are available for free at 🔍: https://infura.io/register
+ *
+ * You'll need a mnemonic - the twelve word phrase the wallet uses to generate
+ * public/private key pairs. You can store your secrets 🤐 in a .env file.
+ * In your project root, run `$ npm install dotenv`.
+ * Create .env (which should be .gitignored) and declare your MNEMONIC
+ * and Infura PROJECT_ID variables inside.
+ * For example, your .env file will have the following structure:
+ *
+ * MNEMONIC = <Your 12 phrase mnemonic>
+ * PROJECT_ID = <Your Infura project id>
+ *
+ * Deployment with Truffle Dashboard (Recommended for best security practice)
+ * --------------------------------------------------------------------------
+ *
+ * Are you concerned about security and minimizing rekt status 🤔?
+ * Use this method for best security:
+ *
+ * Truffle Dashboard lets you review transactions in detail, and leverages
+ * MetaMask for signing, so there's no need to copy-paste your mnemonic.
+ * More details can be found at 🔎:
+ *
+ * https://trufflesuite.com/docs/truffle/getting-started/using-the-truffle-dashboard/
