+# MongoDB::Atlas::StreamWorkspace
+
+## Description
+
+Resource for managing [Stream Workspaces](https://www.mongodb.com/docs/api/doc/atlas-admin-api-v2/group/endpoint-streams).
+
+## Requirements
+
+Set up an AWS profile to securely give CloudFormation access to your Atlas credentials.
+For instructions on setting up a profile, [see here](/README.md#mongodb-atlas-api-keys-credential-management).
+
+## Attributes and Parameters
+
+See the [resource docs](docs/README.md). Also refer [AWS security best practices for CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/security-best-practices.html#creds) to manage credentials.
+
+## CloudFormation Examples
+
+See the examples [CFN Template](/examples/stream-workspace/stream-workspace.json) for example resource.
