 This specification is work in progress and should be considered to be in a beta stage. There is ongoing work to implement this interface in Mbed TLS, which is the reference implementation of the PSA Cryptography API. At this stage, Arm does not expect major changes, but minor changes are expected based on experience from the first implementation and on external feedback.

 Migrating to an auto generated psa_crypto_driver_wrappers.c file
 ================================================================
 
-**This is a specification of work in progress. The implementation is not yet merged into Mbed TLS.**
-
 This document describes how to migrate to the auto generated psa_crypto_driver_wrappers.c file.
 It is meant to give the library user migration guidelines while the Mbed TLS project tides over multiple minor revs of version 1.0, after which this will be merged into psa-driver-interface.md.
 
+For a practical guide with a description of the current state of drivers Mbed TLS, see our [PSA Cryptoprocessor driver development examples](../psa-driver-example-and-guide.html).
+
 ## Introduction
 
 The design of the Driver Wrappers code generation is based on the design proposal https://github.com/Mbed-TLS/mbedtls/pull/5067
