+#############################################
+Use the Library to Adapt Your Training Script
+#############################################
+
+This section contains the SageMaker distributed data parallel API documentation.
+If you are a new user of this library, it is recommended you use this guide alongside
+`SageMaker's Distributed Data Parallel Library
+<https://docs.aws.amazon.com/sagemaker/latest/dg/data-parallel.html>`_.
+
+The library provides framework-specific APIs for TensorFlow and PyTorch.
+
+Select the latest or one of the previous versions of the API documentation
+depending on the version of the library you use.
+
+.. important::
+
+   The distributed data parallel library supports training jobs using CUDA 11 or later.
+   When you define a :class:`sagemaker.tensorflow.estimator.TensorFlow` or
+   :class:`sagemaker.pytorch.estimator.PyTorch`
+   estimator with the data parallel library enabled,
+   SageMaker uses CUDA 11. When you extend or customize your own training image,
+   you must use a base image with CUDA 11 or later. See
+   `SageMaker Python SDK's distributed data parallel library APIs
+   <https://docs.aws.amazon.com/sagemaker/latest/dg/data-parallel-use-api.html#data-parallel-use-python-skd-api>`_
+   for more information.
