-about
------
-  CSSO does structure-optimization for css.
-  (readme and tests/comparison - coming later)
-  Css is usually reduced more that in half in uncompressed and around 15% in gzipped.

+### A Real-World Example
+A living rails application CSS – some written in less, some handwritten):
 
-From ruby:
-  require 'csso'
-  Csso.optimize("a{ color: #FF0000; }")
-  # produces "a{color:red}"
+|        | Original     |  sass  | yui 2.4.7  | csso  | % of original
+|:-------|:------------:|:------:|:-----:|:-----:|:------:
+|Plain   | 129497       | 107006 | 60758 | 60874 | 47%
+|GZipped | 14046        | 12047  | 10558 | 10472 | 74%
 
-In Rails 3.1+:  
-  add this gem to your gemfile, and that's it!
-  gem 'csso-rails', :git => ''
-  Upon including it becomes the default compressor,
-  More explicit way - set in config: config.assets.css_compressor = :csso
+Very close to yui compressor, wining in gzipped (you’re using nginx `mod\_gzip_static`, don’t you?)
 
-In command line:
-  ruby_csso non_optimized.css > optimized.css
+A more hard example – twitter bootstrap.css, already minified:
 
+|        | Original     | lessc | yui 2.4.7  | csso  | % of original
+|:-------|:------------:|:-----:|:-----:|:-----:|:------:
+|Plain   | 81443        | 71520 | 68755 | 67679 | 83%
+|GZipped | 12384        | 11633 | 11652 | 11477 | 92%

+## Usage
+
+### In Rails 3.1+
+add `gem 'csso-rails'` to your gemfile, and that’s it!
+
+Upon including it becomes the default compressor even if sass is included too.
+More explicit way – set in config: `config.assets.css_compressor = :csso`.
+
+
+### In Plain Ruby
+
+```ruby
+ require 'rubygems'
+ gem 'csso-rails'
+ require 'csso'
+ puts Csso.optimize("a{ color: #FF0000; }") # produces "a{color:red}"
+```
+
+In _maniac mode_(`Csso.optimize(css, true)`, default for pipeline) CSS is processed several times until it stops getting lighter (there're cases when original csso does not do all optimizations for no reason).
+
+### In Command Line
+
+    ruby_csso non_optimized.css > optimized.css
