+# Module: Golden Signal Alerts [New]:
+This module encapsulates an alerting strategy based on the [Four Golden Signals](https://landing.google.com/sre/sre-book/chapters/monitoring-distributed-systems/#xref_monitoring_golden-signals) introduced in Google’s widely read book on [Site Reliability Engineering](https://landing.google.com/sre/sre-book/toc/index.html).
+
+The signals chosen for this module are:
+
+* *Latency*: High response time (seconds)
+* *Traffic*: Low throughput (requests/minute)
+* *Errors*: Error rate (errors/minute)
+* *Saturation*: CPU utilization (percentage utilized)
+
+### Requirements
+Applications making use of this module need to be reporting data into both APM and Infrastructure.
+
+### Input variables
+The following input variables are accepted by the module:
+
+* `name`: The APM application name as reported to New Relic
+* `threshold_duration`: The duration, in seconds, that the condition must violate the threshold before creating a violation.
+* `cpu_threshold`: The critical threshold of the CPU utilization condition, as a percentage
+* `error_percentage_threshold`: The critical threshold of the error rate condition, as a percentage
+* `response_time_threshold`: The critical threshold of the response time condition, in seconds
+* `throughput_threshold`: The critical threshold of the throughput condition, in requests/second
+
+### Outputs
+The following output values are provided by the module:
+
+* `policy_id`: The ID of the created alert policy
+* `cpu_condition_id`: The ID of the created high CPU alert condition
+* `error_percentage_condition_id`: The ID of the created error percentage alert condition
+* `response_time_condition_id`: The ID of the created response time alert condition
+* `throughput_condition_id`: The ID of the created throughput alert condition
+
+
+### Example usage
