-If you are not running Debian_ on a particular machine a :ref:`chap_vm` is
-provided as a convenient testing and evaluation environment.  After a few
-simple steps to setup the virtual machine, you will be able to use NeuroDebian_
-as an integral part of your existing working environment without any sacrifice.
-The virtual machine is also a suitable environment to temporarily deploy
-neuroscience software on machines running other operating systems, e.g. for the
-purpose of teaching a neuroimaging data analysis course in a multipurpose
-computer lab.
+For all non-Debian operating systems the recommended way to deploy NeuroDebian
+is a `virtual appliance`_. On all modern hardware (built within the last 3-4
+years) a virtual appliance is a convenient solution to run NeuroDebian
+simultaneously with the primary operating system -- without noticable
+performance loss.
+
+1. Install NeuroDebian by first downloading this image file:
+
+.. raw:: html
 
+  <div id="vmimagedownload">
+  <a href="http://neuro.debian.net/debian/vm/">NeuroDebian images</a>
+  </div>
+
+2. Once downloaded, import this image into your VirtualBox_ installation. If you
+   do not have VirtualBox_ installed yet, visit the `VirtualBox download page
+   <http://www.virtualbox.org/wiki/Downloads>`_ that provides installers for
+   Windows, Linux, Mac and Solaris.
+
+3. Please read :ref:`the detailed instructions on setting up the virtual
+   appliance <chap_vm>` to complete the configuration of your NeuroDebian
+   environment.
+
+.. note::
 
-Debian installation
--------------------
+  If you still running an older VirtualBox 3.x, download one of the image files
+  listed below. These older releases are distributed as a `zip` file. Please
+  extract all files from the `.zip` file, using appropriate software
+  for your operating system.
 
-Having been exposed to the wonders of NeuroDebian_ you are no longer
-satisfied with your previous choice of operating system?  We would
-recommend installing Debian_ to replace or complement (dual-boot) your
-existing OS.  Please visit `"Getting Debian"
-<http://www.debian.org/distrib/>`_ to obtain the images for your
-hardware architecture and then simply add |repos|.
