 MantidImaging
 =============
 
-MantidImaging is a graphical toolkit for performing 3D reconstruction of neutron
-tomography data.
+Mantid Imaging is a graphical toolkit for performing 3D reconstruction of neutron tomography data. It provides an easy-to-use graphical interface to a wide range of pre/post-processing operations, tilt correction and reconstruction algorithms, accommodating for tomography users with varying data complexity and image analysis background knowledge. It utilises a flexible plugin system that allows easy integration of external software, and has allowed us to re-use software widely known in the neutron tomography community.
 
-The toolkit performs the essential image correction/filtering and
-reconstruction. For more general purpose image processing see `Fiji
-<https://fiji.sc/>`_. Volume rendering and visualisation can be done with tools
