+Nitrox Crypto Poll Mode Driver
+==============================
+
+The Nitrox crypto poll mode driver provides support for offloading
+cryptographic operations to the NITROX V security processor. Detailed
+information about the NITROX V security processor can be obtained here:
+
+* https://www.marvell.com/security-solutions/nitrox-security-processors/nitrox-v/
+
+Installation
+------------
+
+For compiling the Nitrox crypto PMD, please check if the
+CONFIG_RTE_LIBRTE_PMD_NITROX setting is set to `y` in config/common_base file.
+
+* ``CONFIG_RTE_LIBRTE_PMD_NITROX=y``
+
+Initialization
+--------------
+
+Nitrox crypto PMD depend on Nitrox kernel PF driver being installed on the
+platform. Nitrox PF driver is required to create VF devices which will
+be used by the PMD. Each VF device can enable one cryptodev PMD.
+
+Nitrox kernel PF driver is available as part of CNN55XX-Driver SDK. The SDK
+and it's installation instructions can be obtained from:
+`Marvell Technical Documentation Portal <https://support.cavium.com/>`_.
