 Here, we show how to use Swiftest's Gravitational Harmonics capabilities. 
-Swiftest uses `SHTOOLS <https://shtools.github.io/SHTOOLS/>` to compute the gravitational harmonics coefficients for a given body and calculate it's associated acceleration kick. 
+Swiftest uses `SHTOOLS <https://shtools.github.io/SHTOOLS/>`__ to compute the gravitational harmonics coefficients for a given body and calculate it's associated acceleration kick. 
 The coefficients can be computed in a number of ways: 
-- Using the axes measurements of the body ( :func: `clm_from_ellipsoid <swiftest.shgrav.clm_from_ellipsoid>`)
-- Using a surface relief grid ( :func: `clm_from_relief <swiftest.shgrav.clm_from_relief>`).
