Which example to use

I managed to get Rasa open source up and running. I trained the model using the dataset that comes with the code from pip3 install rasa. I can see there are examples on GitHub rasa/examples at main · RasaHQ/rasa · GitHub But there is not much information on them. Which one I should download and train that is a good general-purpose chatbot? It will be used for a demo of a commercial web app
