+# You need to set the following variables:
+#   HUBOT_NEWRELIC_ACCOUNT_ID = "<Account ID>"
+#   HUBOT_NEWRELIC_APP_ID     = "<Application ID>"
+#   HUBOT_NEWRELIC_API_KEY    = "<API Key>"
+# 
+# How to find these settings:
+#   After signing into New Relic, select your application
+#   Given: https://rpm.newrelic.com/accounts/xxx/applications/yyy
+#     xxx is your Account ID and yyy is your App ID
+#   Account Settings > API + Web Integrations > API Access > "API key"
