+ (description
+ "SWIFTGalaxy is an astrophysics module that extends
+@url{http://swiftsimio.readthedocs.org/, SWIFTSimIO} tailored to analyses of
+particles belonging to individual galaxies simulated with
+@url{https://swift.strw.leidenuniv.nl/, SWIFT}. It inherits from and extends
+the functionality of the @code{SWIFTDataset}. It understands the content of
+halo catalogues (supported:
+@url{https://ui.adsabs.harvard.edu/abs/2019PASA...36...21E/abstract,
+Velociraptor}, @url{https://caesar.readthedocs.io/en/latest/, Caesar},
+@url{https://github.com/SWIFTSIM/SOAP, SOAP}) and therefore which particles
+belong to a galaxy or other group of particles, and its integrated properties.
+The particles occupy a coordinate frame that is enforced to be consistent,
+such that particles loaded on-the-fly will match e.g. rotations and
+translations of particles already in memory. Intuitive masking of particle
+datasets is also enabled. Utilities to make working in cylindrical and
+spherical coordinate systems more convenient are also provided. Finally,
+tools to iterate efficiently over multiple galaxies are also provided.")
