 This package provides core functionality for interacting with the ThousandEyes API and should be installed before using any of the published SDKs.
 
-`PaginatorIterator` is unbounded, so wrap it with `itertools.islice` to cap the number of items and avoid making unintended, potentially expensive API calls. 
+Usage example for iterating paginated responses:
-Pick a slice size that matches your UI or batch size so you only fetch what you plan to process:
