+     "@code{iminuit} is a Jupyter-friendly Python interface for the @code{Minuit2}
+C++ library maintained by CERN's ROOT team.
+
+Minuit was designed to optimize statistical cost functions, for
+maximum-likelihood and least-squares fits.  It provides the best-fit
+parameters and error estimates from likelihood profile analysis.
+
+Optionally, Iminuit supports SciPy minimizers as alternatives to Minuit's
+MIGRAD algorithm and Numba accelerated functions.")
