 Congratulations! You've successfully built a machine learning model to detect stop signs in images using Model Builder. You can find the source code for this tutorial at the [dotnet/machinelearning-samples](https://github.com/dotnet/machinelearning-samples/tree/main/samples/modelbuilder/ObjectDetection_StopSigns) GitHub repository.
