+Introduction
+************
+
+This repository contains cryptographic drivers that implement the
+PSA Cryptoprocessor Driver Interface, for example, to be further integrated
+within `Trusted-Firmware-M`_ based platforms.
+
+The `PSA Cryptoprocessor Driver Interface`_ is designed to interface with a
+PSA Crypto core component, such as the reference implementation available
+in `TF-PSA-Crypto`_. For more details on the capabilities implemented through
+such interfaces please refer directly to their respective documentation.
+The PSA Crypto core component exposes PSA Crypto APIs, for example
+the `PSA Cryptography API 1.1`_.
+
