------------------------------------------

+Overview
+^^^^^^^^
+The barometer-influxdb image is based on the influxdb:1.3.7 image from the influxdb dockerhub. To
+view detils on the base image please visit
+`https://hub.docker.com/_/influxdb/ <https://hub.docker.com/_/influxdb/>`_ Page includes details of
+exposed ports and configurable enviromental variables of the base image.
+
+The barometer-grafana image is based on grafana:4.6.3 image from the grafana dockerhub. To view
+details on the base image please visit
+`https://hub.docker.com/r/grafana/grafana/ <https://hub.docker.com/r/grafana/grafana/>`_ Page
+includes details on exposed ports and configurable enviromental variables of the base image.
+
+The barometer-grafana image includes pre-configured source and dashboards to display statistics exposed
+by the barometer-collectd image. The default datasource is an influxdb database running on localhost
+but the address of the influxdb server can be modified when launching the image by setting the
+environmental variables influxdb_host to IP or hostname of host on which influxdb server is running.
+
+Additional dashboards can be added to barometer-grafana by mapping a volume to /opt/grafana/dashboards.
+Incase where a folder is mounted to this volume only files included in this folder will be visible
+inside barometer-grafana. To ensure all default files are also loaded please ensure they are included in
+volume folder been mounted. Appropriate example are given in section ``Run the Grafana docker image``
