I’m attempting my first plugin and have come across this in the codebase:

```
{{#discovery-categories refresh="refresh"}}
  {{component categoryPageStyle
              categories=model.categories
              latestTopicOnly=latestTopicOnly
              topics=model.topics}}
{{/discovery-categories}}

```

I’ve done some basic Ember recently, but haven’t come across the `{{#name}}` syntax yet.

I learnt to use components like (without the hash in the name):

```
{{component-name}}

```

Does the hash/pound symbol represent anything special? Is it even a component? And why is the `categoryPageStyle` component being called with ‘component’ in front of it?

Thanks!
