Key4hep Tutorials

This page contains several tutorials for working in a Key4hep software stack. We try to design and set them up in a way that they can be done at any time but we present them at hands-on tutorial sessions as well. This is an incomplete list of all available tutorials, which you can find in the key4hep-tutorials repository.

If you are following these tutorials and run into an issue please let us know by opening an issue on the key4hep-doc repository. If you have the feeling that something is missing, we are also very happy to accept new tutorial suggestions. If you have a tutorial that you would like to add here.
