-If you would like to use a custom sampling function or measurement function in BTK we recommend that you use the python interface (as in the `tutorial <https://lsstdesc.org/BlendingToolKit/tutorials.html>`_). More specifically, the "custom" `tutorial notebook<https://github.com/LSSTDESC/BlendingToolKit/blob/main/notebooks/custom-tutorial.ipynb>`_ include examples for writing a custom sampling function, survey, measure function, and target measure.
