 The following benchmarks were produced on an Intel(R) Core(TM) i7-8569U CPU @ 2.80GHz against SciPy-1.10.1. The dotted line on the right-hand figure shows the expected speedup (4x) from parallelization on a CPU with four physical cores.

 ## Contributions
 
-**You can help with adding more distributions, patches are very welcome.** Implementing a probability distribution is easy. You need to write it in simple Python that `numba` can understand. Special functions from `scipy.special` can be used after some wrapping, see submodule `numba_stats._special.py` how it is done.
