### Default Security Contexts

The default pod-level and container-level security contexts, below, adhere to the [restricted](https://kubernetes.io/docs/concepts/security/pod-security-standards/#restricted) Pod Security Standards policies.

Default pod-level securityContext:
```yaml
runAsNonRoot: true
seccompProfile:

### Installing with a Values file

## TODO

Publish the chart to Artifacthub and add proper installation instructions. E.G.
> **NOTE**: This is not currently a valid installation option.

```console
$ helm repo add answerdev https://charts.answer.dev/
$ helm repo update
$ helm install answerdev/answer -n mynamespace
```
