-Grafana Dashboards for a LOFAR 2.0 station
+# Grafana Dashboards for a LOFAR 2.0 station
+
+These dashboards show the state of a single station. They are tailored to be installed:
+
+* Locally on a station, through https://git.astron.nl/lofar2.0/tango/-/tree/master/docker-compose/grafana
+* Centrally to monitor a group of stations, through https://git.astron.nl/lofar2.0/operations-central-management/-/tree/main/grafana-central/dashboards
+
+## Development
+
+To cover both these use cases, the designer must consider:
+
+* Using a `host="$station"` filter to make sure that centrally, the selected station is shown. On a specific station, this will default to `host="localhost"`,
+* Deploying changes on all stations as well as centrally.
+
+## Deployment
+
+To deploy changes, they must be:
+
+1. Committed to this repository,
+2. The submodules in the tango and operations-central-management repositories must link to the new commit,
+3. Those repositories need to be redeployed on the stations and centrally, respectively.
