Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the
Service OS and Guest OSs. It is a component that is used in conjunction with
the `ACRN Hypervisor`_ and this is installed within the Service OS. You can
find out more about Project ACRN on the `Project ACRN documentation`_ website.
