+# This script connects Domoticz with Google Cloud PubSub API
+# To make it works :
+# 1 - Install the Google API Client Python Library : pip install --upgrade google-api-python-client (or see https://cloud.google.com/pubsub/libraries)
+# 2 - Activate the Google Cloud PubSub API in the Google Cloud Console
+# 3 - Generate a Service account key in the Google Cloud Console and download the private key in JSON format
+# 4 - Transfer the json key into the domoticz install dir
+# 5 - Set the ENV variable GOOGLE_APPLICATION_CREDENTIALS to the path of your Service account key
+# 6 - Create a topic in the "PubSub" Google Cloud Console
+# 7 - Modify the variable PUBSUB_TOPICNAME below with the topic name
