+Prometheus Metrics Plugin
+-------------------------
+
+This is a Prometheus Metrics client ("target").
+
+It provides ("exports") I2P and JVM statistics ("metrics")
+for scraping by the Prometheus server.
+
+You must install prometheus server:
+
+  sudo apt install prometheus
+
+And then add i2p to the prometheus configuration.
+Edit /etc/prometheus/prometheus.yml and add:
+
+  - job_name: i2p
+    scrape_interval: 60s
+    metrics_path: /prometheus/metrics
+    static_configs:
+      - targets: ['localhost:7657']
+
+And then tell prometheus to reload the config:
+
+  sudo killall -HUP prometheus
+
+You should then see i2p listed on the prometheus targets page:
+
+  http://localhost:9090/classic/targets
+
+and see i2p_* and jvm_* metrics to graph at:
+
+  http://localhost:9090/classic/graph
+
+For a nicer dashboard, use Grafana, and add Prometheus Server as a data source.
