Missing info regarding GOOGLE Dialogflow authentication to the app

[popolitodev75]

The readme procedure is not detailed enough to get through an integration with DialogFlow.
All configuration regarding how to set the environment variable GOOGLE_APPLICATION_CREDENTIALS using the json file from GCP platform is missing,
The tutorial given "How to Setup DialogFlow V2 Authentication Programmatically with node.js", shows a really different way to authenticate, which is pretty confusing.
Please add more information to this crucial step of the integration, before so far, I have not been able to get a proper answer from my DialogFlow bot, despite a lot of research over the internet.

Note : the rainbow bot side aspects work perfectly (events, actions, errors...)

Great thanks for your help.

Hi @popolitodev75 , thank you for your feedback,

The tutorial is only referenced in order to point the Setting up Service Account chapter. I just update the readme. Is it sufficient ?
