 ## Overview
 
 Cells allow you to encapsulate parts of your UI into components into _view models_. View models, or cells, are simple ruby classes that can render templates.
 
-Nevertheless, a cell gives you more than just a template renderer. They allow proper OOP, polymorphic builders, [nesting](#nested-cells), view inheritance, using Rails helpers, [asset packaging](http://trailblazer.to/gems/cells/rails.html#asset-pipeline) to bundle JS, CSS or images, simple distribution via gems or Rails engines, encapsulated testing, [caching](#caching), and [integrate with Trailblazer](https://github.com/trailblazer/trailblazer-cells).
