-To use the Viam ML training client API, you first need to instantiate a [`ViamClient`](https://python.viam.dev/autoapi/viam/app/viam_client/index.html#viam.app.viam_client.ViamClient) and then instantiate an [`MLTrainingClient`](https://python.viam.dev/autoapi/viam/app/viam_client/index.html#viam.app.viam_client.ViamClient.ml_training_client).

+To use the Viam ML training client API, you first need to instantiate a `ViamClient` and then instantiate an `MLTrainingClient`.
 
-You can create an [API key](/manage/manage/access/) on your settings page.
+You will also need an API key and API key ID to authenticate your session.
+Your API key needs to have [Org owner permissions](/manage/manage/rbac/#organization-settings-and-roles) to use the MLTraining client API.
+To get an API key (and corresponding ID), you have two options:
+
+- [Create an API key using the Viam app](/operate/control/api-keys/#add-an-api-key)
+- [Create an API key using the Viam CLI](/dev/tools/cli/#create-an-organization-api-key)

+The following example instantiates a `ViamClient`, authenticating with an API key, and then instantiates an `MLTrainingClient`:

 Once you have instantiated an `MLTrainingClient`, you can run the following [API methods](#api) against the `MLTrainingClient` object (named `ml_training_client` in the examples).
