    38  ### Profiles
    39  
    40  Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
    41  These can be set with `--set profile=<profile>`.
    42  For example, the `demo` profile offers a preset configuration to try out Istio in a test environment, with additional features enabled and lowered resource requirements.
    43  
    44  For consistency, the same profiles are used across each chart, even if they do not impact a given chart.
    45  
    46  Explicitly set values have highest priority, then profile settings, then chart defaults.
    47  
    48  As an implementation detail of profiles, the default values for the chart are all nested under `defaults`.
    49  When configuring the chart, you should not include this.
    50  That is, `--set some.field=true` should be passed, not `--set defaults.some.field=true`.
