 ## Running
 
 ### Run everything via `docker-compose`
 
+#### Prerequisites
 * Download `docker-compose.yml` from https://github.com/jaegertracing/jaeger/blob/master/examples/grafana-integration/docker-compose.yml
 * Download the `datasources.yaml` from the `examples/grafana-integration/` folder
+* All services will log to Loki via the loki docker logging plugin.
+To install run this on the host once:
+
+```bash
+docker plugin install \
+grafana/loki-docker-driver:latest \
+--alias loki \
+--grant-all-permissions
+```
+
+#### Deploy the local setup
 * Run Grafana and Loki integration with Jaeger backend using HotROD demo with `docker-compose -f path-to-yml-file up`
 * Access Grafana UI at http://localhost:3000 and HotROD app at http://localhost:8080
