-Prerequisites
-=============
-The OPNFV deployment is out of the scope of this document but it can be
-found in http://docs.opnfv.org.
-The OPNFV platform is considered as the SUT in this document.
-
-Several prerequisites are needed for Functest:
-
-    #. A Jumphost to run Functest on
-    #. A Docker daemon shall be installed on the Jumphost
-    #. A public/external network created on the SUT
-    #. An admin/management network created on the SUT
-    #. Connectivity from the Jumphost to the SUT public/external network
-    #. Connectivity from the Jumphost to the SUT admin/management network
-
-WARNING: Connectivity from Jumphost is essential and it is of paramount
-importance to make sure it is working before even considering to install
-and run Functest. Make also sure you understand how your networking is
-designed to work.
-
-NOTE: **Jumphost** refers to any server which meets the previous
-requirements. Normally it is the same server from where the OPNFV
-deployment has been triggered previously.
-
-NOTE: If your Jumphost is operating behind a company http proxy and/or
-firewall, please consult first the section `Proxy Support`_, towards
-the end of this document. The section details some tips/tricks which
-*may* be of help in a proxified environment.
-
-Docker installation
--------------------
-Docker installation and configuration is only needed to be done once
-through the life cycle of Jumphost.
-
-If your Jumphost is based on Ubuntu, SUSE, RHEL or CentOS linux, please
-consult the references below for more detailed instructions. The
-commands below are offered as a short reference.
-
-*Tip:* For running docker containers behind the proxy, you need first
-some extra configuration which is described in section
-`Docker Installation on CentOS behind http proxy`_. You should follow
-that section before installing the docker engine.
-
-Docker installation needs to be done as root user. You may use other
-userid's to create and run the actual containers later if so desired.
-Log on to your Jumphost as root user and install the Docker Engine
-(e.g. for CentOS family)::
-
- curl -sSL https://get.docker.com/ | sh
- systemctl start docker
-
- *Tip:* If you are working through proxy, please set the https_proxy
- environment variable first before executing the curl command.
-
-Add your user to docker group to be able to run commands without sudo::
-
- sudo usermod -aG docker <your_user>
-
-A reconnection is needed. There are 2 ways for this:
-    #. Re-login to your account
-    #. su - <username>

-Public/External network on SUT
-------------------------------
-Some of the tests against the VIM (Virtual Infrastructure Manager) need
-connectivity through an existing public/external network in order to
-succeed. This is needed, for example, to create floating IPs to access
-VM instances through the public/external network (i.e. from the Docker
-container).
-
-By default, the four OPNFV installers provide a fresh installation with
-a public/external network created along with a router. Make sure that
-the public/external subnet is reachable from the Jumphost.
-
-*Hint:* For the given OPNFV Installer in use, the IP sub-net address
-used for the public/external network is usually a planning item and
-should thus be known. Consult the OPNFV Configuration guide `[4]`_, and
-ensure you can reach each node in the SUT, from the Jumphost using the
-'ping' command using the respective IP address on the public/external
-network for each node in the SUT. The details of how to determine the
-needed IP addresses for each node in the SUT may vary according to the
-used installer and are therefore ommitted here.
-
-Connectivity to Admin/Management network on SUT
------------------------------------------------
-Some of the Functest tools need to have access to the OpenStack
-admin/management network of the controllers `[1]`_.
-
-For this reason, check the connectivity from the Jumphost to all the
-controllers in cluster in the OpenStack admin/management network range.

-Installation and configuration
-==============================
+.. include:: ./prerequisites.rst
 
 .. include:: ./configguide.rst
 
-Integration in CI
-=================
-In CI we use the Docker image and execute the appropriate commands within the
-container from Jenkins.
-
-Docker creation in set-functest-env builder `[3]`_::
-
-    envs="-e INSTALLER_TYPE=${INSTALLER_TYPE} -e INSTALLER_IP=${INSTALLER_IP} -e NODE_NAME=${NODE_NAME}"
-    [...]
-    docker pull opnfv/functest:$DOCKER_TAG >/dev/null
-    cmd="sudo docker run -id ${envs} ${volumes} ${custom_params} ${TESTCASE_OPTIONS} opnfv/functest:${DOCKER_TAG} /bin/bash"
-    echo "Functest: Running docker run command: ${cmd}"
-    ${cmd} >${redirect}
-    sleep 5
-    container_id=$(docker ps | grep "opnfv/functest:${DOCKER_TAG}" | awk '{print $1}' | head -1)
-    echo "Container ID=${container_id}"
-    if [ -z ${container_id} ]; then
-        echo "Cannot find opnfv/functest container ID ${container_id}. Please check if it is existing."
-        docker ps -a
-        exit 1
-    fi
-    echo "Starting the container: docker start ${container_id}"
-    docker start ${container_id}
-    sleep 5
-    docker ps >${redirect}
-    if [ $(docker ps | grep "opnfv/functest:${DOCKER_TAG}" | wc -l) == 0 ]; then
-        echo "The container opnfv/functest with ID=${container_id} has not been properly started. Exiting..."
-        exit 1
-    fi
-
-    cmd="python ${FUNCTEST_REPO_DIR}/functest/ci/prepare_env.py start"
-    echo "Executing command inside the docker: ${cmd}"
-    docker exec ${container_id} ${cmd}
-
+.. include:: ./ci.rst
 
-Test execution in functest-all builder `[3]`_::
 
-    branch=${GIT_BRANCH##*/}
-    echo "Functest: run $FUNCTEST_SUITE_NAME on branch ${branch}"
-    cmd="functest testcase run $FUNCTEST_SUITE_NAME"
-    fi

+Prerequisites
+=============
+The OPNFV deployment is out of the scope of this document but it can be
+found in http://docs.opnfv.org.
+The OPNFV platform is considered as the SUT in this document.
+
+Several prerequisites are needed for Functest:
+
+    #. A Jumphost to run Functest on
+    #. A Docker daemon shall be installed on the Jumphost
+    #. A public/external network created on the SUT
+    #. An admin/management network created on the SUT
+    #. Connectivity from the Jumphost to the SUT public/external network
+    #. Connectivity from the Jumphost to the SUT admin/management network
+
+WARNING: Connectivity from Jumphost is essential and it is of paramount
+importance to make sure it is working before even considering to install
+and run Functest. Make also sure you understand how your networking is
+designed to work.
+
+NOTE: **Jumphost** refers to any server which meets the previous
+requirements. Normally it is the same server from where the OPNFV
+deployment has been triggered previously.
+
+NOTE: If your Jumphost is operating behind a company http proxy and/or
+firewall, please consult first the section `Proxy Support`_, towards
+the end of this document. The section details some tips/tricks which
+*may* be of help in a proxified environment.
+
+Docker installation
+-------------------
+Docker installation and configuration is only needed to be done once
+through the life cycle of Jumphost.
+
+If your Jumphost is based on Ubuntu, SUSE, RHEL or CentOS linux, please
+consult the references below for more detailed instructions. The
+commands below are offered as a short reference.
+
+*Tip:* For running docker containers behind the proxy, you need first
+some extra configuration which is described in section
+`Docker Installation on CentOS behind http proxy`_. You should follow
+that section before installing the docker engine.
+
+Docker installation needs to be done as root user. You may use other
+userid's to create and run the actual containers later if so desired.
+Log on to your Jumphost as root user and install the Docker Engine
+(e.g. for CentOS family)::
+
+ curl -sSL https://get.docker.com/ | sh
+ systemctl start docker
+
+ *Tip:* If you are working through proxy, please set the https_proxy
+ environment variable first before executing the curl command.
+
+Add your user to docker group to be able to run commands without sudo::
+
+ sudo usermod -aG docker <your_user>
+
+A reconnection is needed. There are 2 ways for this:
+    #. Re-login to your account
+    #. su - <username>
