This plugin adds a Chef fact improter to Foreman. It basically means that when you setup your chef clients to use foreman handlers (https://github.com/theforeman/chef-handler-foreman) and install this plugin you receive nested facts. This plugin expects foreman to support nested facts which is currently under review (theforeman/foreman#968). To install this plugin you just have to add this line to your gemfile
gem 'foreman_chef', :git => 'https://github.com/ares/foreman_chef'and run bundle install. Don't forget to restart foreman after this change.
If you want to use this in production I recommend to combine this plugin with foreman-background (https://github.com/ohadlevy/foreman-background) which runs report and facts import as a background tasks. Actually facts importing support is not merged (you can watch status here ohadlevy/foreman-background#1)
