• -d postgresql sets up the project to use PostgreSQL
• --skip-turbolinks & --skip-spring creates a project that does not use turbolinks or spring
• -T skips the creation of the test directory and use of Test::Unit

2. In the Gemfile:

• Available to all environments:
  • gem 'figaro' - store environment variables securely across your app (docs)
  • Uncomment gem 'bcrypt', '~> 3.1.7' if you will be hosting your own user accounts with passwords (docs)
• Inside of group :test:
  • gem 'rspec-rails' - user rspec in place of minitest (docs)
