+      Galario is a library that exploits the computing power of modern
+      graphic cards (GPUs) to accelerate the comparison of model
+      predictions to radio interferometer observations. Namely, it
+      speeds up the computation of the synthetic visibilities given a
+      model image (or an axisymmetric brightness profile) and their
+      comparison to the observations.
