+This package contains methods for modelling the Universe, galaxies and the
+Milky Way. SkyPy simulates populations of astronomical objects, generating
+random realisations of intrinsic and observed properties, with the
+intention the simulations can then be compared to data as part of an inference
+pipeline.
+
+Currently, SkyPy implements the following modules:
 
 * Galaxies_: morphology, luminosity and redshift distributions
 * Pipelines_ to generate populations of astronomical objects
 
-The full list of features can be found in the `SkyPy Documentation`_.
