+Install Fuel
+============
+
+This section describes how to install Fuel on virtual or
+bare-metal hardware. During the installation, you deploy the Fuel Master node
+on the selected hardware and boot the servers or virtual machines that are
+dedicated as Fuel Slave nodes. However, you do not install an operating
+system or OpenStack components on the Fuel Slave nodes just yet. After you
+deploy the Fuel Master node, you create an OpenStack environment using the
+Fuel web UI or Fuel CLI. The Fuel Master node provisions the dedicated Fuel
+Slave nodes with the selected operating system, OpenStack or other
+components and roles when you deploy an OpenStack environment.
