To use kits with interactivity, and our graphs you need to bring in the NPM package.
yarn add "playbook-ui@stable"
This will allow you to choose what version you want.
Now that you have the package installed you could import styles via JS
<%= yield :pb_js %>
Playbook ships with font awesome but you’ll need to include it in your application
//= require regular-min.js //= require fontawesome-min.js
