-How to Store your Custom Translations

-The equivalent YAML file would look like this:

-      short: "%b %d"
-      long: "%B %d, %Y"

-
-So, all of the following equivalent lookups will return the `:short` date format `"%b %d"`:
-
-```ruby
-I18n.t 'date.formats.short'
-I18n.t 'formats.short', scope: :date
-I18n.t :short, scope: 'date.formats'
-I18n.t :short, scope: [:date, :formats]

-
-Generally we recommend using YAML as a format for storing translations. There are cases, though, where you want to store Ruby lambdas as part of your locale data, e.g. for special date formats.

 ### Translations for Active Record Models
 
 You can use the methods `Model.model_name.human` and `Model.human_attribute_name(attribute)` to transparently look up translations for your model and attribute names.

-```ruby
+```yaml
