 ==============
 
 JSON formatter for the ruby 1.9+ coverage gem SimpleCov
+
+Usage
+-----
+
+1. Add simplecov-json to your `Gemfile` and `bundle install`:
+
+        gem 'simplecov-json', :require => false, :group => :test
+
+2. Require simplecov-json and set it up as SimpleCov's formatter: 
+
+        require 'simplecov-json'
+        SimpleCov.formatter = SimpleCov::Formatter::JSONFormatter
+
+Result
+------
+
+Generated JSON can be found in coverage/coverage.json
+
+The format you can expect is:
+
+        {
+            "timestamp": 1348489587,
+            "command_name": "RSpec",

+                {
+                    "filename": "/home/user/rails/environment.rb",
+                    "coverage": [
