+description: A Helm chart to deploy Blockscout proxy-verifier
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+version: 1.0.0
+
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application. Versions are not expected to
+# follow Semantic Versioning. They should reflect the version the application is using.
+# It is recommended to use it with quotes.

+
+A Helm chart to deploy Blockscout ENC application to kubernetes cluster
+
+## Prerequisites
+
+- Kubernetes 1.19+
+- Helm 3+
+<!-- - PostgreSQL version 12 to 14
+- Redis (if accounts blockscout feature is enabled) -->
+
+## Get Helm Repository Info
+
+```console
+helm repo add blockscout https://blockscout.github.io/helm-charts
+helm repo update
+```
+
+_See [`helm repo`](https://helm.sh/docs/helm/helm_repo/) for command documentation._
+
+## Install Helm Chart
+
+```console
+helm install [RELEASE_NAME] blockscout/blockscout-proxy-verifier
+```
+_See [configuration](#configuration) below._
+_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
+## Uninstall Helm Chart
+
+```console
+helm uninstall [RELEASE_NAME]
+```
+_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
+This removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Upgrading Chart
+
+```console
+helm upgrade [RELEASE_NAME] blockscout/blockscout-proxy-verifier
+```
+
+## Configuration
+
+See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments:
+
+```console
+helm show values blockscout/blockscout-proxy-verifier
+```
+This chart does not contain default values for required ENV variables.
