+This :ref:`TRIQS-based <triqslibs:welcome>`-based application is aimed
+at ab-initio calculations for 
+correlated materials, combining realistic DFT band-structure
+calculations with the dynamical mean-field theory. Together with the
+necessary tools to perform the DMFT self-consistency loop for
+realistic multi-band problems, the package provides a full-fledged
+charge self-consistent interface to the `WIEN2K package
+<http://www.wien2k.at>`_. In addition, if Wien2k is not available, it
+provides a generic interface for one-shot DFT+DMFT calculations, where
+only the single-particle Hamiltonian in orbital space has to be
+provided.
