This tutorial is a good starting point from developing Slicer extensions from scratch in Python: [https://www.slicer.org/wiki/Documentation/Nightly/Training#PerkLab.27s\_Slicer\_bootcamp\_training\_materials](https://www.slicer.org/wiki/Documentation/Nightly/Training#PerkLab.27s_Slicer_bootcamp_training_materials)

See [this post](https://discourse.slicer.org/t/fiducial-to-model-surface-distance/9554/8) for information about how to learn underlying libraries.
