+# Extra integration tests for release
+
+This folder contains an extra set of regression tests related to important
+downstream integration use cases that can be run during release to test integration compatibility of the code.
+While most of the tests should be covered by downstream tests and unit tests (UT), it is still helpful to have some
+form of quick integration checks during release.
+
+**High-level summary:**
+
+- This folder should not be used in CI (as it integrates downstream usage tests).
+- We aim to curate this folder to contain a reasonably minimal set
+  that covers representative use cases based on regressions and lessons learned.
+- It is not meant to replace downstream tests, but can help catch issues during release.
