+### Data Cleaning
+
+The UDP provided its raw data as a PostgreSQL dump.
+This [notebook](https://nbviewer.jupyter.org/github/webartifex/urban-meal-delivery/blob/main/notebooks/00_clean_data.ipynb)
+cleans the data extensively
+and maps them onto the [ORM models](https://github.com/webartifex/urban-meal-delivery/tree/main/src/urban_meal_delivery/db)
+defined in the `urban-meal-delivery` package
+that is developed in the [src/](https://github.com/webartifex/urban-meal-delivery/tree/main/src) folder
+and contains all source code to drive the analyses.
+
+Due to a non-disclosure agreement with the UDP,
+neither the raw nor the cleaned data are published as of now.
+However, previews of the data can be seen throughout the [notebooks/](https://github.com/webartifex/urban-meal-delivery/tree/main/notebooks) folders.
