Please reference the MDT 2013 Release Notes as a starting point.
Important! MDT 2013 Update 1 Preview is pre-release software and is only for use in lab environments.
MDT 2013 Update 1 Preview leverages the Windows Assessment and Deployment Kit (ADK) for Windows 10 Technical Preview to support "lite touch installation" (LTI) deployments for Windows 10 Technical Preview, as well as Windows 8 and Windows 7. The Windows ADK for Windows 10 Technical Preview is a prerequisite and available for download from the Microsoft Download Center.
This preview does not support integration with System Center Configuration Manager for "zero-touch installation" (ZTI) or "user-driven installation" (UDI) scenarios.
You can upgrade to MDT 2013 Update 1 from MDT 2013 (remember, lab only!).
(more coming soon)
See this post for information to unblock MDT with the 10041 ADK and OS builds.
