    Configuration allows you to tweak Spree's behavior without having to modify the source code.

    Spree comes with a handful configuration options you can change:

    To change these you need to edit your `config/initializers/spree.rb` file.

    For example, to disable the `expedited_exchanges` feature, you would add the following line:

    ```ruby
    Spree.config do |config|
      config.expedited_exchanges = false
    end
    ```
