+### MCSP
+
+To use the SDK through a third party cloud provider (such as AWS), use the `MCSPAuthenticator`. This will require the base endpoint URL for the MCSP token service (e.g. https://iam.platform.saas.ibm.com) and an apikey. 
+
+```python
+from ibm_watson import AssistantV2
+from ibm_cloud_sdk_core.authenticators import MCSPAuthenticator
+
+# In the constructor, letting the SDK manage the token
+authenticator = MCSPAuthenticator('apikey', 'token_service_endpoint')
