 ### Reloading in Rails Applications
 
+#### Rails 7+ (Zeitwerk)
+
+Rails 7+ uses [Zeitwerk](https://github.com/fxn/zeitwerk) as the default autoloader, which automatically handles reloading of code in development mode without any additional configuration.
+
+If your API files are in `app/api`, Zeitwerk will automatically autoload and reload them. No additional configuration is needed.
+
+If you encounter issues with reloading, ensure that:
+
+1. Your API files follow Zeitwerk naming conventions (file names should match class names).
+2. The `config.enable_reloading` is set to `true` in `config/environments/development.rb` (this is the default).
+
+For troubleshooting autoloading issues, have a look at the [Rails documentation](https://guides.rubyonrails.org/autoloading_and_reloading_constants.html#troubleshooting).
+
+See the [Rails Autoloading and Reloading Constants guide](https://guides.rubyonrails.org/autoloading_and_reloading_constants.html) for more information.
+
+#### Rails 6 and Earlier
+
+For Rails versions before 7, you need to configure reloading manually.
+
 Add API paths to `config/application.rb`.
