+# Staging threadnetwork HAL interface
+
+The directory includes the unstable/unreleased version of `hardware/interfaces/threadnetwork`
+code which should **NOT** be used in production. But vendors may start verifying their hardware
+with the HAL interface.
+
+This directory will be cleaned up when the stable Thread HAL interface is added in
+`hardware/interfaces/threadnetwork` by version `V` or later.
