    The latest development version of Boto3 is on `GitHub <https://github.com/boto/boto3>`_.
 
+Using the AWS Common Runtime (CRT)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In addition to the default install of Boto3, you can choose to include the new `AWS Common Runtime <https://docs.aws.amazon.com/sdkref/latest/guide/common-runtime.html>`_
+(CRT). The AWS CRT is a collection of modular packages that serve as a new foundation for AWS SDKs.
+Each library provides better performance and minimal footprint for the functional area it
+implements. Using the CRT, SDKs can share the same base code when possible, improving consistency
+and throughput optimizations across AWS SDKs.
+
+When the AWS CRT is included, Boto3 uses it to incorporate features not otherwise
+available in the AWS SDK for Python.
+
+At this time, Boto3 uses the AWS CRT's authentication package (`aws-c-auth
+<https://github.com/awslabs/aws-c-auth>`_) to add support for the `AWS Signature Version 4
+<https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html>`_ (sigv4) signer, which
+adds authentication to your AWS requests using your security credentials (your AWS access key and
+secret access key).
+
+Boto3 doesn't use the AWS CRT by default but you can opt into using it by specifying the
+:code:`crt` `extra feature <https://www.python.org/dev/peps/pep-0508/#extras>`_ when installing Boto3::
+
+    pip install boto3[crt]
+
+To revert to the non-CRT version of Boto3, use this command::
+
+    pip uninstall awscrt
+
+If you need to re-enable CRT,  reinstall :code:`boto3[crt]` to ensure you get a compatible version of :code:`awscrt`::
+
+    pip install boto3[crt]
+
