+# Substrate Prometheus Exporter
+
+## Introduction
+
+[Prometheus](https://prometheus.io/) is one of the most widely used monitoring tools for managing highly available
+services supported by [Cloud Native Computing Foundation](https://www.cncf.io/). By providing Prometheus metrics in
+Substrate, node operators can easily adopt widely used display/alert tools such as [Grafana](https://grafana.com/) and
+[Alertmanager](https://prometheus.io/docs/alerting/alertmanager/). Easy access to such monitoring tools will benefit
+teyrchain developers/operators and validators to have much higher availability of their services.
+
+Metrics will be served under `/metrics` on TCP port 9615 by default.
+
+## Quick Start
+
+1. From the root of the repository start Substrate `cargo run --release`.
+
+2. In another terminal run `curl localhost:9615/metrics` to retrieve the metrics.
+
+To learn how to configure Prometheus see the Prometheus [Getting
+Started](https://prometheus.io/docs/prometheus/latest/getting_started/) guide.
