 ## Production
 
-The features are produced in [phrase_heads.ipynb](phrase_heads.ipynb). This notebook is run against BHSA version `c`. The choice to keep production within Jupyter notebooks is a strategic one. The heads feature will not be complete until the subphrase data model is fixed. This is because the data model behind subphrases suffers problems of incompleteness and inconsistency (see explanations below). While the vast majority of issues with heads has been solved, there will need to be continuous corrections, experimentation, and improvements. Furthermore, the in-depth analysis of these notebooks will be useful when underlying data changes in successive updates. Thus, it would be a mistake to hide the heads production in a .py script. For the time being, the production code should live together with the analysis and interactions available in a Jupyter notebook. The production of phrase_atom heads requires some modifications to the templates, and phrase_atoms present a whole new set of unique situations to account for.  
+The features are produced in [generate_phrase_heads.ipynb](generate_phrase_heads.ipynb). This notebook is run against BHSA versions `c` and `2021`.
