 ### Iterative tuning of a RAG indexing pipeline
 
 A [**notebook**](./src/evaluation.ipynb) which iteratively runs a Fondant
-[indexing pipeline](./src/pipeline_index.py) and [evaluation pipeline](./src/pipeline_eval.py) with 
-different parameters for comparison. You can inspect the data between every step to make 
-informed choices on which parameters to try.
