+# Prometheus Metrics
+
+This configuration file can be used to set up a Prometheus instance to read
+data from  Nomad cluster, using Consul for service discovery.
+
+Requirements:
+  - See Prometheus's
+    [Getting Started](https://prometheus.io/docs/introduction/getting_started/)
+    guide for instructions on how to set up a Prometheus server.
+  - This configuration is written assuming there is a local Consul agent being
+    run along side the Prometheus server. If this is not the case, the
+    configuration will need to be updated to point at the remote Consul agent.
