### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
These can be set with `--set profile=<profile>`.
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.
