+TrueCharts can be installed as both _normal_ Helm Charts or as TrueNAS SCALE Apps.
+Both solutions are fully supported, but we heavily advice the use of normal Helm Charts where possible

+
+**This chart is not maintained by the upstream project and any issues with the chart should be raised [here](https://github.com/truecharts/charts/issues/new/choose)**
