Google Assistant: Qwik Start - Dialogflow
The instructions were a bit unclear while creating the diagflow action
The Italian localization is incorrect (the laboratory is not completed successfully) and the screenshots would need to be changed (new online version of dialogflow)
Great job building your first Google Assistant application! You got a high level overview of the Actions console, Dialogflow, and the other components that go into creating a Google Assistant Application. In just 30 minutes you were able to build your own quotation generator, not bad for just starting out.
