+# Summary
+
+Pyradiosky is a package to fully and generally describe models of compact,
+extended and diffuse foregrounds with full polarization support. It
+emphasizes the provenance and metadata required to understand the errors and
+covariances associated with foreground models built from interferometric data.
+
+# Statement of need
+
+The original motivation for the development of pyradiosky was to support
+high-precision simulation of interferometric data for 21 cm cosmology, but was
+deliberately developed to support a broad range of radio astronmy applications.
+Foreground models are key to the future of 21 cm analyses because high-precision
+foreground subtraction has the potential to dramatically increase the sensitivity
+of 21 cm instruments. High-quality foreground models are also extremely
+important for calibration of all radio astronomy data.
+
+Pyradiosky supports reading in catalogs in the widely used VOTable format as
+well as an HDF5 based format we developed. It also supports some formats used by
+21 cm cosmology codes and is easily extensible to other formats. It provides an
+object interface and useful methods for downselecting and combining multiple
+catalogs, coordinate transformations (with polarization support) and calculating
+fluxes at specific frequencies.
+
+As part of the Radio Astronomy Software Group suite (along with pyuvdata
+[@pyuvdata2017] and pyuvsim [@pyuvsim2019]), pyradiosky provides software
+infrastructure for a broad range of radio astronomy applications including
+enabling rigorous, seamless testing of 21 cm cosmology analysis developments.
