+
+optional arguments:
+  -h, --help   show this help message and exit
+  -d, --debug  Debug mode
+
+Actions
+ * start: will prepare the functional testing environment
+ * check: will check the configuration (scenarios available, environment variables properly set, networks,..)
+ * clean: will clean the functional test environement if existing
 
 This script will:
- * Check the environment
- * Install tools
+ * Install Rally environment
+ * Install Tempest
  * Retrieve test scenarios
- * Upload cloud images
- * Create temporary test networks
+ * Setup ODL environment
+ * Create temporary neutron external network
+ * Create temporary neutron private network
+ * Create router to connect both
+ * Create Glance images

+
+The procedure to set up functional testing environment can be described as follow::
 
     Log on the Jumphost server
+    Be sure you are no root
     $ wget https://git.opnfv.org/cgit/functest/plain/testcases/config_functest.py
     $ wget https://git.opnfv.org/cgit/functest/plain/testcases/functest.yaml
+    Modify and adapt needed parameters in the functest.yaml. Follow the instructions below.
     Retrieve OpenStack source file (configure your `OpenRC`_ file to let Rally access to your OpenStack, you can either export it from Horizon or build it manually (OpenStack credentials are required)
     $ source Your_OpenRC_file
-    $ python config_functest.py start
+    $ python config_functest.py -d start
+
+At the end of the executing, a new directory will be created ~/.functest with the following structure::
+
+ ~/.functest/ODL
+ ~/.functest/Rally_repo
+ ~/.functest/Rally_test
+ ~/.functest/vPing
+ ~/.functest/functest.yaml
+ ~/.functest/trusty-server-cloudimg-amd64-disk1.img
+
+NOTE: the Rally environment will be installed under ~/.rally/
+
+
+HOWTO configure functest.yaml:
+
+Do not change the directories structure
+    * image_name:               name of the image that will be created in Glance
+    * image_url:                URL of the image to be downloaded
+    * image_disk_format:        glance image disk format (raw, qcow2, ...)
+
+    * neutron_public_net_name:      name of the OpenStack external network. If not existing, it will be created
+    * neutron_public_subnet_name:   external network subnet to be created if not existing
+    * neutron_public_subnet_cidr:   range of the external subnet. IMPORTANT: this subnet range must be reachable from the jumpstart server
+    * neutron_public_subnet_start:  start IP
+    * neutron_public_subnet_end:    end IP
+
+    * neutron_private_net_name:     name of an OpenStack private network. If not existing, it will be created
+    * neutron_private_subnet_name:  private subnet network to be created if not existing
+    * neutron_private_subnet_cidr:  range of the private subnet.
+    * neutron_private_subnet_start: start IP
+    * neutron_private_subnet_end:   end IP
+    * neutron_router_name:          name of the router between the private and the public networks
 
-At the end of the configuration, you shall get the .functest repository::
+    * ping_timeout: time out of the vPing test case
+    * vm_flavor:    name of the flavor used to create the VMs
+    * vm_name_1:    name of the first VM
+    * vm_name_2:    name of the second VM
