 Will match "Apple iPad" first with the /Apple/ matcher, then with the /iPad/ matcher, and the tags will be
-    
+
     [:apple, :iphone_os, :ipad] # Notice tags get appended, *not* overridden.
 
 And _:format_ will be set to _nil_
 
 Why _nil_? Because when :format is set to _nil_ and you ask for it, DiviningRod will return the original _request_ objects format.

+## Writing your own custom profiler
 
-In version 0.3.* it was assumed you always passed in _format_. In 0.4 on, we require _format_ to
-be passed in explicitly with the rest of the options hash.
+You can also include the DiviningRod::Profiler mixin in your own custom class
