text: Title: How to build Interactive Chatbot with Chatterbot
  Body: Hi Team,
  I am developing a ChatBot for Our DevOps Team, which will be hosted in our internal Infrastructure i.e. on Intranet.
  Our Requirement is to have chatbot with fixed responses, e.g. the user has to select from the given option only. Like dominos app.
  Please help me how to build it and please share any example of chatterbot + Flask with this kind of use case.
