 # LeptonInjector
 
 LeptonInjector is a framework for injecting and weighting interaction final states of complex topology, with specific concern for the detector geometry. LeptonInjector is designed to support a wide variety of neutrino experimental setups, including atmospheric neutrinos, accelerator beam decay-in-flight neutrinos, and neutrinos from decay-at-rest sources. The original [LeptonInjector-v1](https://github.com/icecube/LeptonInjector) was developed within the IceCube collaboration to study atmospheric and astrophysical neutrino interactions in the IceCube detector.
