 ### Add annotations programmatically
 
-You can programmatically add a new annotation to the PDF document by creating an annotation instance and providing it as a parameter to the `addAnnotation` method of the `PdfViewerController` class. The following example shows how to create an instance of a highlight annotation and add it to the PDF document. Similarly, you can create and add other types of annotation.
