+# Zephyr RTOS Integration
+
+This directory contains metadata to allow CMSIS_6 to be consumed as a
+module by the Zephyr RTOS.
+
+## Purpose
+
+The files in this directory exist solely to support integration with
+Zephyr's build system. They enable Zephyr to include CMSIS_6 as an
+external module without requiring any modifications to the CMSIS_6
+source tree.
+
+## Scope
+
+- This directory is **only used by Zephyr**.
+- It does **not** affect CMSIS_6 functionality or usage outside of Zephyr.
+- It is intentionally minimal to avoid introducing any dependencies on
+  Zephyr within the rest of the CMSIS_6 repository.
+
+## CMake and Kconfig
+
+Any references to CMake or Kconfig in this directory are specific to Zephyr's
+module integration mechanism. Zephyr-specific build logic is kept outside of
+the CMSIS_6.
+
+## More Information
+
+For details on Zephyr and its modules, see:
+- https://docs.zephyrproject.org/latest/
+- https://docs.zephyrproject.org/latest/develop/modules.html
