Ember-formly Addon's component isn't found

I'm am trying to get the ember-formly addon working like the readme.md file for that addon shows. So, I:

1. Ran ember install ember-formly
2. Dumped the example form data Model() and fields into my application/controller.js file
3. Put the basic template data into my templates/application.hbs file

And that gives me this error when I load it up in my browser:

Assertion Failed: Could not find component named "custom-fields/html-input" (no component or template with that name was found)

Being rather new to Ember.js I'm sure I'm missing something simple... Any ideas? Thanks!
