 ## Advanced Configuration Options
 
 The `TranslationIO.configure` block in `config/initializers/translation.rb` can take several optional configuration options.
 
+### Disable GetText
 
+Sometimes, you only want to use YAML and don't want to be bothered by GetText at all.
+For these cases, you just have to add `disable_gettext` in the config file.

+For example:
+
+    TranslationIO.configure do |config|
+      ...
+      config.disable_gettext = true
+      ...
+    end
 
 ### Ignored YAML keys
 
 Sometimes you would like to ignore some YAML keys coming from gems or so.
 You can use the `ignored_key_prefixes` for that.

 ### Custom localization key prefixes
