+The propagator class in `adam_core` provides a generalized interface to the supported orbit integrators and ephemeris generators. The propagator class is designed to be used with the `Orbits` class and can handle multiple orbits and times. 
+
+You will need to install either adam_core[pyoorb] or adam_core[assist], or another compatible propagator in order to use propagation, ephemeris generation, or impact analysis.

 #### Ephemeris Generation
-The propagator class can also be used to generate ephemerides for a set of orbits and observers.
+Ephemeris generation requires a propagator that implements the EphemerisMixin interface. This is currently only implemented by the PYOORB propagator. The ephemeris generator will automatically map the propagated covariance matrices to the sky-plane.

+You will need to install adam-pyoorb in order to use the ephemeris generator.
