+This is a gem for Rails >= 3.1 applications. It provides all the basic DataTables files, but not (yet) the extras.
+
+# Install and Usage
+
+First, put the gem in your Gemfile (`gem 'jquery-datatables-rails'`) and run `bundle install`
+
+After installing it you can require it in your _application.js_ file with `\\= require jquery.dataTables.min`, or use the images and stylesheets in the _dataTables_ directory: `<%= image_tag 'dataTables/sortBoth.png' %>`
+
+# Plugins
+
+Right now, the only plugin that is available is fnReloadAjax. Check out the [assets directory][assets].
