Installation ============ .. index:: Installation RTEMS is built from source on your host machine. Releases are available from our :r:url:`ftp` and each release contains a Quick Start build guide. If you are wanting to track changes to RTEMS as they happen or you want to make changes to RTEMS to send back to the project on our :r:list:`devel` then you can use the developer's version available in our :r:url:`git`. RTEMS supports development on a wide vararity of hosts. There is no preferred host operating system the project requires you use. This means you are able to decide on a host operating system that is your passion, suites your needs, or in some cases is decided for you by your employer. Our aim is to provide a consistent user experience and on matching hardware the experience should feel similar. The RTEMS core development team uses POSIX type operating systems, that is Unix. The :ref:`released-version` and :ref:`development-version` sections assume Unix. Microsoft Windows is documented in a separate section :ref:`microsoft-windows-installation`.
