-1. Set up an [IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create.html) and provide it access to the OpenSearch cluster using Signature Version 4 authentication.
+1. Set up an [IAM user or an IAM Role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create.html) and provide it access to the OpenSearch cluster using Signature Version 4 authentication.
 
 2. Set up the following environment variables for your IAM user:
 
    ```bash
-   OSB_AWS_ACCESS_KEY_ID=<IAM USER AWS ACCESS KEY ID>
-   OSB_AWS_SECRET_ACCESS_KEY=<IAM USER AWS SECRET ACCESS KEY>
