+# Docker Hub Exporter
+
+Opinionated helm chart for [`jessestuart/docker-hub-exporter`](https://github.com/jessestuart/docker-hub-exporter).
+
+## Configuration
+
+While the underlying docker image supports specific docker images this helm chart only lets you configure 
+`organisations`. There are also two dashboards included, one for InfluxDB and one for Prometheus.
+
+### Sample configuration
+
+```yaml
+organisations: wyrihaximusnet
+
+grafana:
+  prometheus: true
+```
+
+## Opinionated decisions
+
+* Port is hardcoded to `9170` for the metrics.
+* Only gather metrics for full organizations and users.
