+Exasol AI-Lab comes with a set of Jupyter Notebook Files with file extension `.ipynb` demonstrating AI applications on top of the Exasol database.  Additionally, the demos in the Exasol AI-Lab require some credentials and other configuration strings which are managed in a [Secure Configuration Storage](secure-configuration-storage.md) (SCS).
 
 By default, the AI-Lab will instantiate the notebook files with a predefined content. The predefined content may change with each release of the AI-Lab. However, the AI-Lab won't overwrite existing files.
 
 The SCS on the other hand will be populated by the Exasol AI-Lab, including manual input from the user but also entries generated by the Exasol AI-Lab.
