# helpGuideContentId

The key for the content identifier of the help guide entry that a person opened.

```
static let helpGuideContentId: String
```

## Discussion

Use this value to distinguish entries when several help guide entries in your `metadata.json` file share one [`HomeAccessoryHelpGuide`](/documentation/HomeExtensions/HomeAccessoryHelpGuide) identifier. The metadata omits this key if the entry has no `ContentId`.
