 \todo{Will be written once we know which examples we have}
 
+To demonstrate the properties of the code and its capabilities, we have used it to simulate common astrophysical configurations of interest.  Given the community-oriented direction of the project, the parameter files required to launch these simulations and a host of others are included and documented in the code releases, along with the datafiles produced by a representative set of simulation parameters to allow for code validation and confirmation of correct code performance on new platforms and architetures.  As part of the internal validation process, 
+nightly builds are checked against a set of benchmarks to ensure that consistent results are generated with the inclusion of all new commits to the code.

 As a first example we perform simulations of a single distorted rotating BH.
