     GEPA is an evolutionary optimizer, which uses reflection to evolve text components
     of complex systems. GEPA is proposed in the paper [GEPA: Reflective Prompt Evolution Can Outperform Reinforcement Learning](https://arxiv.org/abs/2507.19457).
+    The GEPA optimization engine is provided by the `gepa` package, available from [https://github.com/gepa-ai/gepa](https://github.com/gepa-ai/gepa).
 
     GEPA captures full traces of the DSPy module's execution, identifies the parts of the trace
     corresponding to a specific predictor, and reflects on the behaviour of the predictor to
