-A Pulumi Resource Provider for The Pulumi Service.
+Pulumi Service Provider for creating Pulumi Cloud resources.
 
-The Pulumi Service Provider is built on top of the [Pulumi Service REST API](https://pulumi.com/docs/reference/service-rest-api) which is another feature available to our customers to programmatically configuring the Pulumi Service. The Pulumi Service REST API includes functionality to interact with and manipulate any kind of metadata managed by Pulumi. That includes Projects and Stacks, Previews and Updates, Organizations and Audit Logs. We have already seen Cloud Engineering teams using the Pulumi REST API to build all sorts of custom functionality. These new capabilities are especially powerful when used in combination with the [Automation API](https://pulumi.com/automation).

That includes Stacks, Environments, Teams, Tokens, Webhooks, Tags, Deployment Settings, Deployment Schedules and much more!
