-# JSON Builder
+JSON Builder
+============
 Rails provides an excellent XML Builder by default to build RSS and ATOM feeds, but nothing to help you build complex and custom JSON data structures. The standard `to_json` works just fine, but can get very verbose when you need full control of what is generated and performance is a factor. JSON Builder hopes to solve that problem.
 
 ## Sample Usage
 
 ```ruby
 require 'json_builder'
 
 json = JSONBuilder::Compiler.generate do
   name "Garrett Bjerkhoel"
   email "[e-mail]"
+  url root_path
   address do
     street "1234 1st Ave"
     street2 "Apt 1"
     city "New York"
     state "NY"
