 SPICE relies on a set of user-supplied input files (kernels) to perform its calculations. A number of these kernels are installed automatically with Tudat, and loaded when calling the :func:`~tudatpy.interface.spice.load_standard_kernels` function (see this API docs entry for list of kernels).
+To extend the standard kernels, a user can download additional kernels from other sources such as `NAIF directly <https://naif.jpl.nasa.gov/naif/data_generic.html>`_ or the `JPL Horizons System <https://ssd.jpl.nasa.gov/horizons/app.html#/>`_ for small-body objects, and then load them using the :func:`~tudatpy.interface.spice.load_kernel` function.
 
 When using the default kernels/body settings, we have introduced one small difference for the sake of expediency. For the cases of Uranus, Neptune and Pluto, where we only have the ephemeris of the barycenter of the planetary system loaded, the planet is placed at the barycenter of the planetary system. This introduces a minor offset in the position of this planet (Mercury and Venus have no moons, and therefore their state coincides with their planetary system barycenter; dedicated planetary system ephemerides are loaded for the Earth, Mars, Jupiter and Saturn system). For Uranus, for example, the default settings will place Uranus at the center of mass (barycenter) of the combined system of Uranus and its moons. To correct this behaviour, a user can load a kernel for this body's planetary system (see `here <https://naif.jpl.nasa.gov/pub/naif/generic_kernels/spk/satellites/>`__, for example), and modify the default settings.
