 Testing
 -------
 
-First start a local Elasticsearch:
+In another terminal use docker-compose to start an Elasticsearch instance :
 
 ```bash
-$ bin/elasticsearch
+docker-compose up
+```
+
+For convenience, you can also start a Kibana instance for analysis/visualization :
+
+```bash
+docker-compose -f docker-compose.yml -f docker-compose-kibana.yml up
 ```
 
 Run Common Test:
 
 ```bash
-$ rebar3 ct
+rebar3 ct
 ```
