+[![Build Status](https://drone.cryptic.systems/api/badges/volker.raschek/postfixadmin-charts/status.svg)](https://drone.cryptic.systems/volker.raschek/postfixadmin-charts)
+[![Artifact Hub](https://img.shields.io/endpoint?url=https://artifacthub.io/badge/repository/volker-raschek)](https://artifacthub.io/packages/search?repo=volker-raschek)
+
+This is an inofficial helm chart for
+[postfixadmin](https://github.com/postfixadmin/postfixadmin), because the
+maintainer does not provide currently an official one.
+
+This helm chart can be found on [artifacthub.io](https://artifacthub.io/) and
+can be installed via helm.
+
+```bash
+helm repo add volker.raschek https://charts.cryptic.systems/volker.raschek
+helm install postfixadmin volker.raschek/postfixadmin
+```
+
+## Customization
+
+The list below is only an excerpt of the listed environment variables from the
+used [container image](https://github.com/volker-raschek/postfixadmin-docker).
+
+The environment variables are composed on the key of the PHP configuration with
+the prefix `POSTFIXADMIN_`. You can take an example
+[configuration](https://github.com/postfixadmin/postfixadmin/blob/master/config.inc.php)
+from the upstream project.

+## Postfixadmin-Fetchmail
+
+As addon can be additionally the helm chart
+`volker.raschek/postfixadmi-fetchmail` installed. The the `fetchmail.pl` script
+has been packaged into an own container to support among others non-kubernetes
+based postfixadmin instances with the `fetchmail.pl` script on kubernetes basis.
+
+More about the addon is documented
+[here](https://github.com/volker-raschek/postfixadmin-fetchmail-charts).
