 Using the Config object
--------------------------
+-----------------------
 This option is for configuring client-specific configurations that affect the behavior of your specific client object only. As described earlier, there are options used here that will supersede those found in other configuration locations:
 
 * ``region_name`` (string) - The AWS Region used in instantiating the client. If used, this takes precedence over environment variable and configuration file values. But it doesn't overwrite a ``region_name`` value *explicitly* passed to individual service methods.
 * ``signature_version`` (string) - The signature version used when signing requests. Note that the default version is Signature Version 4. If you're using a presigned URL with an expiry of greater than 7 days, you should specify Signature Version 2.
-* ``s3`` (related configurations; dictionary) - Amazon S3 service-specific configurations. For more information, see the `Config reference <https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html>`_.

 * ``retries`` (dictionary) - Client retry behavior configuration options that include retry mode and maximum retry attempts. For more information, see the :ref:`guide_retries` guide.

+Using proxies

+With Boto3, you can use proxies as intermediaries between your code and AWS. Proxies can provide functions such as filtering, security, firewalls, and privacy assurance.

+Specifying proxy servers
+''''''''''''''''''''''''
+
+You can specify proxy servers to be used for connections when using specific protocols. The ``proxies`` option in the ``Config`` object is a dictionary in which each entry maps a protocol to the address and port number of the proxy server for that protocol.
+
+In the following example, a proxy list is set up to use ``proxy.amazon.com``, port 6502 as the proxy for all HTTP requests by default. HTTPS requests use port 2010 on ``proxy.amazon.org`` instead.

+Configuring proxies
+'''''''''''''''''''
+You can configure how Boto3 uses proxies by specifying the ``proxies_config`` option, which is a dictionary that specifies the values of several proxy options by name.  There are three keys in this dictionary: ``proxy_ca_bundle``, ``proxy_client_cert``, and ``proxy_use_forwarding_for_https``. For more information about these keys, see the `Botocore config reference <https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config>`_.
