      # Credo automatically checks for updates, like e.g. Hex does.
      # You can disable this behaviour below:
      check_for_updates: true,
      #
      # If you want to enforce a style guide and need a more traditional linting
      # experience, you can change `strict` to `true` below:
      strict: false,
      #
      # If you want to use uncolored output by default, you can change `color`
      # to `false` below:
      color: true,
      #
      # You can customize the parameters of any check by adding a second element
      # to the tuple.
      #
      # To disable a check put `false` as second element:
