+# Cloudian metrics exporter
+
+This Prometheus exporter provides a metrics endpoint with metrics from a [Cloudian](https://cloudian.com/) installation.
+
+**Note**: This is not affiliated in any way with Cloudian and Cloudian does not offer support for this.
+
+## Configuration
+
+The exporter requires the following configuration using environment variables:
+
+* CLOUDIAN_URL: Cloudian CMC REST api base URL (e.g. https://cmc.company.com:19443)
+* CLOUDIAN_USERNAME: REST api username (usually sysadmin)
+* CLOUDIAN_PASSWORD: REST api password
+* EXPORTER_REFRESH: Interval (in minutes) in which the metric values are updated [5]
+* EXPORTER_LOGLEVEL: Loglevel to use [info]
+* EXPORTER_LISTEN: Port to listen to [8080]
+
+## Usage
+
+Aside from building the go binary and running it, a container is available as well. Run it using e.g.:
+
+   docker run --rm -it -P -e CLOUDIAN_URL=... -e CLOUDIAN_USERNAME=... -e CLOUDIAN_PASSWORD=... ghcr.io/dodevops/cloudian-exporter:main
