 Network policies can only take effect, when the used CNI plugin support network policies. The chart supports no custom
 network policy implementation of CNI plugins. It's support only the official API resource of `networking.k8s.io/v1`.
 
 The example below is an excerpt of the `values.yaml` file. The network policy contains ingress rules to allow incoming

+### Prometheus
+
+Reposilite is not able to expose metrics by default. Reposilite requires an additional plugin to expose the metrics via
+`/metrics`. The plugin will be downloaded from Apache Maven Central, when the plugin is enabled directly or the
+Prometheus feature has been enabled. The plugin is a simple JAR file, which will be stored in `/app/data/plugins`.
+
+Furthermore, Reposilite will not expose the metrics without protection. For this reason must be defined basic auth
+credentials. By default generate the helm chart a random username and password for basic auth. For debugging propose can
+be set the credentials manually.
+
+The following example enable Prometheus metrics with custom basic auth credentials:
+
+```bash
+CHART_VERSION=0.1.3
+helm install --version "${CHART_VERSION}" reposilite volker.raschek/reposilite \
+  --set 'prometheus.metrics.enabled=true' \
+  --set 'prometheus.metrics.basicAuthUsername=my-username' \
+  --set 'prometheus.metrics.basicAuthUsername=my-password'
+```
