+## Fallbacks for empty translations ##
+
+If you have translations in your database (by using the [spree-simple_product_translations](https://github.com/jeroenj/spree-simple_product_translations) extension for example) with empty translations (being a blank string instead of `nil`) you might want to add this configuration option to an initializer in your app:
+
+    Spree::Config.set :fallbacks_for_empty_translations => true
+
+It will then use fallbacks for empty strings too.
+
 ## Running tests ##
 
 The tests are not updated since the original fork of the spree 0.11 compatible version. They will pretty sure fail. Feel free to fork the project and create a pull request with tests.
