You need to be comfortable with Python language, which you can learn in a few days from tutorials on the web. Then the rest is about getting to know libraries. Slicer mainly relies on VTK (that you can learn from VTK [textbook](https://vtk.org/documentation/) and [examples](https://lorensen.github.io/VTKExamples/site/)), ITK (for image processing, that you can learn from the [ITK software guide](https://itk.org/ITKSoftwareGuide/html/)), and Qt (for GUI; which you can learn from Qt documentation and examples). Slicer adds a little extra layer and logic, which you can learn from studying Slicer programming tutorials, script repository, and source code of Slicer core and extensions.

The tutorial that I linked above is a good starting point and you can always ask questions here. You can also come to one of the [Slicer project weeks](https://projectweek.na-mic.org/) where you bring your own problem that you work on with help from Slicer experts.
