+     "Python implementation of Parker wind models for planetary atmospheres.
+@code{p-winds} produces simplified, 1-D models of the upper atmosphere of a
+planet, and perform radiative transfer to calculate observable spectral
+signatures.
+
+The scalable implementation of 1D models allows for atmospheric retrievals to
+calculate atmospheric escape rates and temperatures.  In addition, the modular
+implementation allows for a smooth plugging-in of more complex descriptions to
+forward model their corresponding spectral signatures (e.g., self-consistent
+or 3D models).")
