+IONIC Crypto Driver
+============
+
+The ionic crypto driver provides support for offloading cryptographic operations
+to hardware cryptographic blocks on AMD Pensando server adapters.
+It currently supports the below models:
+
+- DSC-25 dual-port 25G Distributed Services Card `(pdf) <https://pensandoio.secure.force.com/DownloadFile?id=a0L4T000004IKurUAG>`__
+- DSC-100 dual-port 100G Distributed Services Card `(pdf) <https://pensandoio.secure.force.com/DownloadFile?id=a0L4T000004IKuwUAG>`__
+- DSC-200 dual-port 200G Distributed Services Card `(pdf) <https://www.amd.com/system/files/documents/pensando-dsc-200-product-brief.pdf>`__
+
+Please visit the AMD Pensando web site at https://www.amd.com/en/accelerators/pensando for more information.
+
+Device Support
+----------------
+
+The ionic crypto PMD currently supports running directly on the device's embedded
+processors. It does not yet support host-side access via PCI.
+For help running the PMD, please contact AMD Pensando support.
