Wrapping npm modules as Ember Addons

I am working on an Ember application and would like to create an ember addon for it. The use case for the addon would be to create an ontology tree for the consuming application. The repository for the module I would like to make into an addon is inspire tree and I am needing to wrap this module.

Inspire Tree Repository ===> (https://github.com/helion3/inspire-tree).

I am aware of the general structure of Ember addons and an idea on how to make one, but if anyone can give advice on best practices & how to wrap npm modules as addons in general would be very helpful.
