+render_anywhere
+====================
+
+Out of the box, Rails can render templates in a controller context only. This little gem allows for calling "render" from anywhere: models, background jobs, rake tasks, you name it.
+
+Installation
+------------------
+
+    gem install render_anywhere
+
+Usage
+--------------------
+
+Put render_anywhere in your Gemfile: 
+
+    gem 'render_anywhere', :require => false
+
+In your Rails app, in a rake task, model, background job, or where ever you like, require render_anywhere, include the module and call render with the same arguments as ActionController::Base#render takes. It will return a string.
+
+    require 'render_anywhere'
+
+    class AnyClass
+      include RenderAnwhere
+
+      def build_html
+        html = render :template => 'normal/template/reference',
+                      :layout => 'application'
+        html
+      end
+    end
+
+Thanks

+The basic approach used here came from [this gist](https://gist.github.com/977181) by [Julien Guimont aka juggy](https://github.com/juggy). Thanks!
