+## ACI SystemTest Automation on Baremetal VMs
+
+This document is Guide to perform Automation of Systemtests for ACI mode of netplugin and netmaster on Baremetal VMs.
+Current systemtests (github.com/contiv/netplugin/systemtests) rely on vagrant VMs. For ACI testing , We need to have connectivity
+to APIC and ACI Fabric Switches from Baremetal VMs and Hosts.
+
+
+### PreRequisites:
+
+These are One time steps only.
+
+This ACI SystemTest automation works on Baremetal VMs which have met some criteria before. You need to make sure to have all these
+prerequisites satisfied before running automation suite.
+
+* You need to complete Pre-requisites, Step 1, Step 2, Step3 metioned here : https://github.com/contiv/demo/tree/master/net
+* Once you have cfg.yml ready you can run Swarm setup creation script like this.
+  ```
+  ./net_demo_installer -ar
+  ```
+* Let us assume You have 3 Node Swarm Cluster.
+
+So have these Environment variables on Node 1
+
+```
+export HOST_IPS="<IP of Nodes seperate by ,>"
+export HOST_USER_NAMES="<User names of Nodes seperate by ,>"
+export HOST_DATA_INTERFACE="<Data interface of Node 1>"
+export GOPATH=/home/admin
+export GOBIN=$GOPATH/bin
+export PATH=$PATH:$GOBIN:/usr/local/go/bin
+export ACI_SYS_TEST_MODE=ON
+export DOCKER_HOST=<DOCKER_HOST and port output of running ./net_demo_installer -ar>
+
+  for eg: export DOCKER_HOST=10.193.246.4:2375
+
+export KEY_FILE=<Full path of Private key file used in SSH configuration>
+
+  for eg: export KEY_FILE=/home/admin/.ssh/id_rsa
+```
+
+Have these Environment variables on Node 2 and Node 3
+```
+export DOCKER_HOST=10.193.246.4:2375
+```  
+
+* Please check out Netplugin code under : $GOPATH/src/github.com/contiv/ on Node1
+
+* Please make sure all Nodes has $GOBIN directory already created.
+
+### How to Run ACI Systemtests Automation
+
+These are the steps you need to run everytime you are running system-test infra.
+
+* Build the code on Node 1. You can run from $GOPATH/src/github.com/contiv/netplugin
+```
+make run-build
+```
+* Run Systemtests like this
+```
+godep go test -v -timeout 240m ./systemtests -check.v -check.f "<Name of ACI Test Function>"
+for eg :
+
+godep go test -v -timeout 240m ./systemtests -check.v -check.f "TestACIMode"
+
+	This will run TestACIMode test function metioned in systemtests/aci_test.go
+
+godep go test -v -timeout 240m ./systemtests -check.v -check.f "TestACI"
+
+	This will run all the test function which are Starting from TestACI
+```
+
+### Troubleshooting
+
+* First delete all netmaster, netctl, netplugin, contivk8s binaries from $GOBIN directory from All Nodes in Cluster
+* You can perform following steps to clear etcd states
+```
+sudo etcdctl rm --recursive /contiv
+sudo etcdctl rm --recursive /contiv.io
+sudo etcdctl rm --recursive /docker
+sudo etcdctl rm --recursive /skydns
+```
+* You can restart the nodes (sudo /sbin/shutdown -r now)
+* Run net_demo_installer script with -ar option again to launch Swarm cluster and all other services properly.
+  This infra basically relies on this script to start all the services correctly and then it kills netplugin and netmaster
+  services and start those from the source binaries which you build.
