If you are beginning your journey with Senzing, please start with Senzing Quick Start guides.
The Senzing Garage is where projects are "tinkered" on. Although these GitHub repositories may help you understand various approaches to using Senzing, they are not considered to be "production ready" and are not considered to be part of the Senzing product. Heck, they may not even be appropriate for your application of Senzing!
For assistance with any Senzing Garage repository, use the repository's GitHub Discusssions for general discussions or GitHub Issues to report a bug or make a feature request.
