+vACL - Installation Guide
+============================
+
+vACL Compilation
+===================
+
+After downloading (or doing a git clone) in a directory (samplevnf)
+
+###### Dependencies
+* DPDK 16.04: Downloaded and installed via vnf_build.sh or manually from [here](http://fast.dpdk.org/rel/dpdk-16.04.tar.xz)
+Both the options are available as part of vnf_build.sh below.
+* libpcap-dev
+* libzmq
+* libcurl
+
+###### Environment variables
+
+Apply all the additional patches in 'patches/dpdk_custom_patch/' and build dpdk
+
+::
+  export RTE_SDK=<dpdk 16.04 directory>
+  export RTE_TARGET=x86_64-native-linuxapp-gcc
+
+This is done by vnf_build.sh script.
+
+Auto Build:
+==========
+$ ./tools/vnf_build.sh in samplevnf root folder
+
+Follow the steps in the screen from option [1] --> [8] and select option [7]
+to build the vnfs.
+It will automatically download DPDK 16.04 and any required patches and will setup
+everything and build vACL VNFs.
+
+Following are the options for setup:
+
+::
+
+  ----------------------------------------------------------
+   Step 1: Environment setup.
+  ----------------------------------------------------------
+  [1] Check OS and network connection
+
+  ----------------------------------------------------------
+   Step 2: Download and Install
+  ----------------------------------------------------------
+  [2] Agree to download
+  [3] Download packages
+  [4] Download DPDK zip (optional, use it when option 4 fails)
+  [5] Install DPDK
+  [6] Setup hugepages
+
+  ----------------------------------------------------------
+   Step 3: Build VNF
+  ----------------------------------------------------------
+  [7] Build VNF
+
+  [8] Exit Script
+
+An vACL executable will be created at the following location
+samplevnf/VNFs/vACL/build/vACL
+
+
+Manual Build:
+============
+1. Download DPDK 16.04 from dpdk.org
+   - http://dpdk.org/browse/dpdk/snapshot/dpdk-16.04.zip
+2. unzip  dpdk-16.04 and apply dpdk patch
+   - cd dpdk-16.04
+	 - patch -p0 < VNF_CORE/patches/dpdk_custom_patch/rte_pipeline.patch
+ 	 - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-link-management.patch
+	 - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-Rx-hang-when-disable-LLDP.patch
+ 	 - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-link-status-change-interrupt.patch
+ 	 - patch -p1 < VNF_CORE/patches/dpdk_custom_patch/i40e-fix-VF-bonded-device-link-down.patch
+   - build dpdk
+	- make config T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc
+	- cd x86_64-native-linuxapp-gcc
+	- make
+   - Setup huge pages
+	- For 1G/2M hugepage sizes, for example 1G pages, the size must be specified
+          explicitly and can also be optionally set as the default hugepage size for
+          the system. For example, to reserve 8G of hugepage memory in the form of
+          eight 1G pages, the following options should be passed to the kernel:
+		* default_hugepagesz=1G hugepagesz=1G hugepages=8  hugepagesz=2M hugepages=2048
+	- Add this to Go to /etc/default/grub configuration file.
+	  - Append "default_hugepagesz=1G hugepagesz=1G hugepages=8 hugepagesz=2M hugepages=2048"
+	    to the GRUB_CMDLINE_LINUX entry.
+3. Setup Environment Variable
+   - export RTE_SDK=<samplevnf>/dpdk-16.04
+   - export RTE_TARGET=x86_64-native-linuxapp-gcc
+   - export VNF_CORE=<samplevnf>
+     or using ./toot/setenv.sh
+4. Build vACL VNFs
+   - cd <samplevnf>/VNFs/vACL
+   - make clean
+   - make
+5. The vACL executable will be created at the following location
+   - <samplevnf>/VNFs/vACL/build/vACL
+
+Run
+====
+
+Setup Port to run VNF:
+----------------------
+::
+  1. cd <samplevnf>/dpdk-16.04
+  3. ./tool/dpdk_nic_bind.py --status <--- List the network device
+  2. ./tool/dpdk_nic_bind.py -b igb_uio <PCI Port 0> <PCI Port 1>
+  .. _More details: http://dpdk.org/doc/guides-16.04/linux_gsg/build_dpdk.html#binding-and-unbinding-network-ports-to-from-the-kernel-modules
+
+  Make the necessary changes to the config files to run the vACL VNF
+  eg: ports_mac_list = 00:00:00:30:21:00 00:00:00:30:21:00 
+
+ACL
+--------------
+Update the configuration according to system configuration.
+
+::
