 The `@controller` decorator doesn't do all that much. Catalyst components are just "Custom Elements" under the hood, and the `@controller` decorator saves you writing some boilerplate that you'd otherwise have to write by hand. Specifically the `@controller` decorator:
 
  - Derives a tag name based on your class name, removing the trailing `Element` suffix and lowercasing all capital letters, separating them with a dash.
- - Calls `window.customElements.register` with your class, and the newly tag name.
+ - Calls `window.customElements.register` with the newly derived tag name and your class.
  - Injects a call to `bind(this)` inside of the `connectedCallback()` of your class; this ensures that as your element connects it picks up any `data-action` handlers. See [actions](/guide/actions) for more on this.
