 there which are boring to type directly in Slim. The usage is simple:
 
 ```ruby
 == sg_usemin_css('application.css', alt: '.tmp') do |usemin|
   - usemin << 'styles/bootstrap.css'
-  - usemin << 'styles/main.css', 'data-customattr' => 'customdata'
+  - usemin.add 'styles/main.css', 'data-customattr' => 'customdata'
 ```
 
+**Note:** You can either use **&lt;&lt;** or `add`, I prefer the first one but if you want use two params,
+the only way to do it is in this way:
+```ruby
+- usemin.<<('param1', 'data-customattr' => 'customdata')
+```
+Which I consider quite horrible, so the method is aliased with `add`
+
+**Anyway!**  
 The first argument is required, and it's the `path` :
 
 ```html
 <!-- build:<type>(alternate search path) <path> -->
 ```
