 * Uncomment block of code below if you want to use `.env` file during development.
 * You should copy `config/.env.example` to `config/.env` and set/modify the

 *
 * The purpose of the .env file is to emulate the presence of the environment
 * variables like they would be present in production.
 *
 * If you use .env files, be careful to not commit them to source control to avoid
 * security risks. See https://github.com/josegonzalez/php-dotenv#general-security-information
 * for more information for recommended practices.
