-# Helm Charts for Answer project
+# answer

+An open-source knowledge-based community software. You can use it quickly to build Q&A community for your products, customers, teams, and more.
+## Prerequisites
+
+- Kubernetes 1.20+
+## Configuration
+
+The following table lists the configurable parameters of the answer chart and their default values.
+
+| Parameter | Description | Default |
+| --------- | ----------- | ------- |
+| `replicaCount`  | Number of answer replicas  | `1` |
+| `image.repository` | Image repository | `answerdev/answer` |
+| `image.pullPolicy` | Image pull policy | `Always` |
+| `image.tag` | Image tag | `latest` |
+| `env` | Optional environment variables for answer | `LOG_LEVEL: INFO` |
+| `extraContainers` | Optional sidecar containers to run along side answer | `[]` |
+| `persistence.enabled` | Enable or disable persistence for the /data volume | `true` |
+| `persistence.accessMode` | Specify the access mode of the persistent volume | `ReadWriteOnce` |
+| `persistence.size` | The size of the persistent volume | `5Gi` |
+| `persistence.annotations` | Annotations to add to the volume claim | `{}` |
+| `imagePullSecrets` | Reference to one or more secrets to be used when pulling images | `[]` |
+| `nameOverride` | nameOverride replaces the name of the chart in the Chart.yaml file, when this is used to construct Kubernetes object names. |  |
+| `fullnameOverride` | fullnameOverride completely replaces the generated name. |  |
+| `serviceAccount.create` | If `true`, create a new service account | `true` |
+| `serviceAccount.annotations` | Annotations to add to the service account | `{}` |
+| `serviceAccount.name` | Service account to be used. If not set and `serviceAccount.create` is `true`, a name is generated using the fullname template |  |
+| `podAnnotations` | Annotations to add to the answer pod | `{}` |
+| `podSecurityContext` | Security context for the answer pod | `{}` refer to [Default Security Contexts](#default-security-contexts) |
+| `securityContext` | Security context for the answer container | `{}` refer to [Default Security Contexts](#default-security-contexts) |
+| `service.type` | The type of service to be used | `ClusterIP` |
+| `service.port` | The port that the service should listen on for requests. Also used as the container port. | `80` |
+| `ingress.enabled` | Enable or disable ingress. | `false` |
+| `resources` | CPU/memory resource requests/limits | `{}` |
+| `autoscaling.enabled` | Enable or disable pod autoscaling. If enabled, replicas are disabled. | `false` |
+| `nodeSelector` | Node labels for pod assignment | `{}` |
+| `tolerations` | Node tolerations for pod assignment | `[]` |
+| `affinity` | Node affinity for pod assignment | `{}` |
+
+### 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:
+  type: RuntimeDefault
+```
+
+Default containerSecurityContext:
+```yaml
+allowPrivilegeEscalation: false
+capabilities:
+  drop:
+  - ALL
+```
+### Installing with a Values file
+
+```console
+$ helm install answer -f values.yaml .
+```
+> **Tip**: You can use the default [values.yaml]
+
+## 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
+```
