 It's not possible to set values (from `values.yaml`) directly. 
 If you would like to set a lot of values, it's more convenient to write a separate shalm chart.
 * `shalm` doesn't track installed charts on a kubernetes cluster. It works more like `kubectl apply`
+* The `.Release.Name` value is build as follows: `<chart.name>-<chart.suffix>`. If no suffix is given, the hyphen is also ommited.
