How to share the style guide to ember engines

I am working on an ember project where we have a style guide and we are trying to make that available to our app. The app has a number of engines and I am creating an in-repo addon that will have shared components.

I'm trying to add the style guide to the shared addon and make the styles available/accessible to the host app, the engines, and the components in the shared addon.

Can someone provide me some inputs on this?
