-# 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.
