 (also you may want to add some javascript runtime for ExecJS to pick up, like `gem 'therubyracer'`)
 
 Upon including it becomes the default compressor even if sass is included too.
-More explicit way – set in config: `config.assets.css_compressor = :csso`.

 ### Sprockets
 
 If you use Sprockets without Rails:
 
 ```ruby
 require 'csso'
-Csso::CssCompressor.register!
-sprockets_env.css_compressor = :csso
+Csso.install(sprockets_env)
 ```
 
 ### In Plain Ruby
 
 ```ruby
 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).
