 ## Usage
 
 In any Mongoid document, do this:
 
-```
+```ruby
 include Mongoid::Archivable
 ```
 
 Now a `destroy` of a document will move the document to an Archive collection, namespaced under the document you're destroying.
 
 You can restore an archive as well. Send the `.restore` message to it. For now the archived document is retained, but that might change in the future.
 
 ## Example
 
-```
+```ruby
 user = User.create! name: "Example User"
 user.destroy
 
 User.count # => 0
 User::Archive.count # => 1
