-## TIME ZONES
+## Time Zones
 
 Chronic allows you to set which Time class to use when constructing times. By
 default, the built in Ruby time class creates times in your system's local
 time zone. You can set this to something like ActiveSupport's
 [TimeZone](http://api.rubyonrails.org/classes/ActiveSupport/TimeZone.html)
 class to get full time zone support.
 
-    >> Time.zone = "UTC"
-    >> Chronic.time_class = Time.zone
-    >> Chronic.parse("June 15 2006 at 5:45 AM")
-    => Thu, 15 Jun 2006 05:45:00 UTC +00:00
-
+```
+>> Time.zone = "UTC"
+>> Chronic.time_class = Time.zone
+>> Chronic.parse("June 15 2006 at 5:45 AM")
+=> Thu, 15 Jun 2006 05:45:00 UTC +00:00
+```
 
-## LIMITATIONS
+## Limitations
 
 Chronic uses Ruby's built in Time class for all time storage and computation.
 Because of this, only times that the Time class can handle will be properly
 parsed. Parsing for times outside of this range will simply return nil.
 Support for a wider range of times is planned for a future release.
