+  This project is supported by the [Datadog Open Source Program](https://www.datadoghq.com/partner/open-source/).
+
+  As part of this collaboration, Datadog provides a dedicated sandbox account that we use for automated integration and acceptance testing. This contribution allows us to continuously validate changes against a real Datadog environment, improving reliability and reducing the risk of regressions.
+
+  We are grateful to Datadog for supporting our open source ecosystem and helping ensure that infrastructure code for Terraform remains stable and well-tested
