This gem just includes Highcharts as an asset in the Rails 3.1 (or newer) asset pipeline. Highcharts is not free for commercial use, so make sure you have a valid license to use Highcharts.
If you are looking to include Highstock, Justin Kuepper has made highstock-rails, so check it out.
Add the gem to the Gemfile
