 ## Building MITK Diffusion from source
+
+Please not that we moved away from a separate MITK Diffusion application and are instead building configurations of the MITK Workbench. In a (near)-future version of MITK, customizations of the Workbench will be possible to change the display and executable name etc.
+A workaround is to use the MITK branch https://github.com/MITK/MITK/tree/feature/T30337-WorkbenchCustomizations2, which already enables some of those customizations but the final mechanism fot that will be different.
