在Ember中创建一个模态对话框

I'm trying to open a modal dialog form in Ember - I have a form that I'd like users to submit a comment to before processing a workflow, but so far I've been unable to find any good documentation on how to open a modal dialog (where to put controllers, routes, models, etc.). I am new to Ember, so please bear with me. Thanks.I'm trying to open a modal dialog form in Ember
