+Installation
+------------
+
+To build DPDK with the AESNI_GCM_PMD the user is required to install
+the ``libisal_crypto`` library in the build environment.
+For download and more details please visit `<https://github.com/01org/isa-l_crypto>`_.
 
 Initialization
 --------------
 
 In order to enable this virtual crypto PMD, user must:
 
-* Export the environmental variable AESNI_MULTI_BUFFER_LIB_PATH with the path where
-  the library was extracted.
-
-* Build the multi buffer library (go to Installation section in AES-NI MB PMD documentation).
+* Install the ISA-L crypto library (explained in Installation section).
 
 * Set CONFIG_RTE_LIBRTE_PMD_AESNI_GCM=y in config/common_base.
 
 To use the PMD in an application, user must:
 
-* Call rte_eal_vdev_init("crypto_aesni_gcm") within the application.
+* Call rte_vdev_init("crypto_aesni_gcm") within the application.
 
-* Use --vdev="crypto_aesni_gcm" in the EAL options, which will call rte_eal_vdev_init() internally.
+* Use --vdev="crypto_aesni_gcm" in the EAL options, which will call rte_vdev_init() internally.
 
 The following parameters (all optional) can be provided in the previous two calls:
