 As a prerequisite, we will assume that you already have a working deployment of the [docker-tar1090](https://github.com/sdr-enthusiasts/docker-tar1090) or [docker-adsb-ultrafeeder](https://github.com/sdr-enthusiasts/docker-adsb-ultrafeeder) container to receive ADSB data. Optionally, if you are using [docker-dump978](https://github.com/sdr-enthusiasts/docker-dump978) to receive UAT data, you can also include this in your Grafana setup.
 
 For Grafana to work, you will need to install and configure a few extra things:
+
 - ensuring that your `docker-tar1090`, `docker-adsb-ultrafeeder`, and/or `docker-dump978` containers are set up so they make data available to Prometheus
 - a (containerized) Prometheus database instance that reads data from `docker-tar1090`, `docker-adsb-ultrafeeder`, and/or `docker-dump978`
 - a (containerized) Grafana instance that is the platform for creating and hosting the graphs
 - a Grafana Dashboard that contains the actual graphs
