[Jiří Suchomel]

Willingness to contribute

Yes. I can contribute a documentation fix independently.

URL(s) with the issue

https://mlflow.org/docs/latest/getting-started/logging-first-model/step5-synthetic-data.html

Description of proposal (what needs changing)

The call to generate_apple_sales_data_with_promo_adjustment is missing. It's mentioned in the notebook, but not in the HTML code

[Ben Wilson]

It's in the notebook: https://mlflow.org/docs/latest/getting-started/logging-first-model/notebooks/logging-first-model.html

[Jiří Suchomel]

Yes, I know it's in the notebook, I even mentioned it in the description.
I think the HTML tutorial should reflect the final notebook version though.
