 The *host computer* is the thing you use to develop applications.  It runs all
 your tools, editors, documentation viewers, etc.  To get started with RTEMS
-development you need other tools.  This includes a native C, C++ and Python
-development environment.  Please make sure that you can build native C/C++
-applications on your host computer.  You must be able to build native Python C
-modules.  Usually you have to install a Python development package for this.
-Please have a look at the :ref:`Host Computer <host-computer>` chapter for the
-glory details.  In particular :ref:`Microsoft Windows <microsoft-windows>` user
-should do this.
