+This module provides the entire Python SDK for Arvados. The most useful modules
+include:
+
+* arvados.api - After you `import arvados`, you can call `arvados.api` as a
+ shortcut to the client constructor function `arvados.api.api`.
+
+* arvados.collection - The `arvados.collection.Collection` class provides a
+ high-level interface to read and write collections. It coordinates sending
+ data to and from Keep, and synchronizing updates with the collection object.
+
+* arvados.util - Utility functions to use mostly in conjunction with the API
+ client object and the results it returns.
+
+Other submodules provide lower-level functionality.
