 # Machine learning for Eventdisplay
 
+[![LICENSE](https://img.shields.io/badge/License-BSD_3--Clause-blue.svg)](https://github.com/Eventdisplay/Eventdisplay-ML/blob/main/LICENSE)
+[![release](https://img.shields.io/github/v/release/eventdisplay/eventdisplay-ml)](https://github.com/Eventdisplay/Eventdisplay-ML/releases)
+[![pypi](https://badge.fury.io/py/eventdisplay-ml.svg)](https://badge.fury.io/py/eventdisplay-ml)
+
 Toolkit to interface and run machine learning methods together with the Eventdisplay software package for gamma-ray astronomy data analysis.
 
 Provides examples on how to use e.g., scikit-learn or XGBoost regression trees to estimate event direction, energies, and gamma/hadron separators.
