+# Contrib Runtime Components
+
+This directory contains contributed runtime components.
+- It is developing as a PoC or experimental purposes, but not part of officially maintained code yet.
+- It was maintained before, but it is moved to contrib to make it clear that they are not officially supported. It remains to help history tracking and code reference.
+
+These are not maintained by the CI/CD infra except for format checks.
