+Abstract
+========
+
+This document contains details about how to use OPNFV Fuel - Euphrates
+release - after it was deployed. For details on how to deploy check the
+installation instructions in the :ref:`references` section.
+
+This is an unified documentation for both x86_64 and aarch64
+architectures. All information is common for both architectures
+except when explicitly stated.
+
+
+
+================
+Network Overview
+================
+
+Fuel uses several networks to deploy and administer the cloud:
+
++------------------+-------------------+---------------------------------------------------------+
+| Network name     | Deploy Type       | Description                                             |
+|                  |                   |                                                         |
++==================+===================+=========================================================+
+| **PXE/ADMIN**    | baremetal only    | Used for booting the nodes via PXE                      |
++------------------+-------------------+---------------------------------------------------------+
+| **MCPCONTROL**   | baremetal &       | Used to provision the infrastructure VMs (Salt & MaaS). |
+|                  | virtual           | On virtual deploys, it is used for Admin too (on target |
+|                  |                   | VMs) leaving the PXE/Admin bridge unused                |
++------------------+-------------------+---------------------------------------------------------+
+| **Mgmt**         | baremetal &       | Used for internal communication between                 |
+|                  | virtual           | OpenStack components                                    |
++------------------+-------------------+---------------------------------------------------------+
+| **Internal**     | baremetal &       | Used for VM data communication within the               |
+|                  | virtual           | cloud deployment                                        |
++------------------+-------------------+---------------------------------------------------------+
+| **Public**       | baremetal &       | Used to provide Virtual IPs for public endpoints        |
+|                  | virtual           | that are used to connect to OpenStack services APIs.    |
+|                  |                   | Used by Virtual machines to access the Internet         |
++------------------+-------------------+---------------------------------------------------------+
+
+
+These networks - except mcpcontrol - can be linux bridges configured before the deploy on the
+Jumpserver. If they don't exists at deploy time, they will be created by the scripts as virsh
+networks.
+
+Mcpcontrol exists only on the Jumpserver and needs to be virtual because a DHCP server runs
+on this network and associates static host entry IPs for Salt and Maas VMs.
+
+
+
+===================
+Accessing the Cloud
+===================
+
+Access to any component of the deployed cloud is done from Jumpserver to user *ubuntu* with
+ssh key */var/lib/opnfv/mcp.rsa*. The example below is a connection to Salt master.
+
+   .. code-block:: bash
+
+       $ ssh -o StrictHostKeyChecking=no -i  /var/lib/opnfv/mcp.rsa  -l ubuntu 10.20.0.2
+
+**Note**: The Salt master IP is not hard set, it is configurable via INSTALLER_IP during deployment
+
+
+The Fuel baremetal deploy has a Virtualized Control Plane (VCP) which means that the controller
+services are installed in VMs on the baremetal targets (kvm servers). These VMs can also be
+accessed with virsh console: user *opnfv*, password *opnfv_secret*. This method does not apply
+to infrastructure VMs (Salt master and MaaS).
+
+The example below is a connection to a controller VM. The connection is made from the baremetal
+server kvm01.
+
+   .. code-block:: bash
+
+       $ ssh -o StrictHostKeyChecking=no -i  /var/lib/opnfv/mcp.rsa  -l ubuntu x.y.z.141
+       ubuntu@kvm01:~$ virsh console ctl01
+
+User *ubuntu* has sudo rights. User *opnfv* has sudo rights only on aarch64 deploys.
+
+
+=============================
+Exploring the Cloud with Salt
+=============================
+
+To gather information about the cloud, the salt commands can be used. It is based
+around a master-minion idea where the salt-master pushes config to the minions to
+execute actions.
+
+For example tell salt to execute a ping to 8.8.8.8 on all the nodes.
+
+.. figure:: img/saltstack.png
+
+Complex filters can be done to the target like compound queries or node roles.
+For more information about Salt see the :ref:`references` section.
+
+Some examples are listed below. Note that these commands are issued from Salt master
+with *root* user.
