# pluginInstanceAddedToDocument()

Notifies your plug-in when it becomes part of user’s document.

```
optional func pluginInstanceAddedToDocument()
```

## Discussion

Called when a new plug-in instance is created or a document is loaded and an existing instance is deserialized. When the host calls this method, the plug-in is a part of the document and the various API objects work as expected.
