+## Distributed
+
+In this example tempo is configured in a distributed manner, where modules are
+running as separate components and configured to write data to S3 via MinIO,
+which presents an S3 compatible API.
+
+1. First start up the distributed stack.
+
+```console
+docker-compose up -d
+```
+
+At this point, the following containers should be spun up -
+
+```console
+docker-compose ps
+```
+```

+
+2. If you're interested you can see the wal/blocks as they are being created.  Navigate to minio at
+http://localhost:9001 and use the username/password of `tempo`/`supersecret`.
+
+3. The synthetic-load-generator is now printing out trace ids it's flushing into Tempo.  To view its logs use -
+
+```console
+docker-compose logs -f synthetic-load-generator
+```
+```
+synthetic-load-generator_1  | 20/10/24 08:27:09 INFO ScheduledTraceGenerator: Emitted traceId 57aedb829f352625 for service frontend route /product

+```
+
+Logs are in the form
+
+```
+Emitted traceId <traceid> for service frontend route /cart
+```
+
+Copy one of these trace ids.
+
+4. Navigate to [Grafana](http://localhost:3000/explore) and paste the trace id to request it from Tempo.
+Also notice that you can query Tempo metrics from the Prometheus data source setup in Grafana.
+
+5. To stop the setup use -
+
+```console
+docker-compose down -v
+```
