You’d want to use the outlet to add a link to a route which you define in your plugin using a route map, with the route map being done a lot like this:
https://meta.discourse.org/t/multiple-routes-in-one-plugin/38120?u=leomca
That then allows you to define templates, controllers and routes with the same name as your resources. As some examples of defining things in a route map, this would probably be the simplest I’ve written and this the most complex.
You’ll also want to install the ember inspector to debug any routing problems you have.
