# Activeadmin Poro Decorator

Alternative for draper, if you need decorators at ActiveAdmin (and Rails).
Active Admin uses the Draper gem for [decorators](http://activeadmin.info/docs/11-decorators.html), but sometimes you don't need that.
For reasons you could read this article: http://thepugautomatic.com/2014/03/draper.

See discussion of PORO with Active Admin authors [here](https://github.com/activeadmin/activeadmin/issues/3600).

## Installation

Add this line to your application's Gemfile:

```ruby

```

And then execute:
