+# 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.

+# This is the chart version. This version number should be incremented each time you make changes

+# Versions are expected to follow Semantic Versioning (https://semver.org/)

+# This is the version number of the application being deployed. This version number should be

+## Features
+
+- Actively maintained by [GraphOps](https://graphops.xyz) and contributors
+- Deploys a scalable pool of `statefulset` instances, with auto-scaling support
+- Strong security defaults (non-root execution, ready-only root filesystem, drops all capabilities)
+- Readiness checks to ensure traffic only hits `Pod`s that are healthy and ready to serve requests
+- Support for `PodMonitor`s to configure Prometheus to scrape metrics ([prometheus-operator](https://github.com/prometheus-operator/prometheus-operator))
+- Support for configuring Grafana dashboards for polygon ([grafana](https://github.com/grafana/helm-charts/tree/main/charts/grafana))
+
+## Quickstart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm repo add graphops http://graphops.github.io/launchpad-charts
+$ helm install my-release graphops/heimdall-v2
+```
+
+Once the release is installed, heimdall will begin syncing from snapshot if the following was specified:
+```fromSnapshot:
+    # -- Enable initialising Heimdall from a remote Snapshot
+    enabled: true
+    # -- URL to snapshot to download and extract, see [here](https://snapshots.matic.today)
+    snapshotUrl:
+```
+You can use `kubectl logs` to monitor the download status. See the Values section to install Prometheus `PodMonitor`s and a Grafana dashboard.
+
+## Upgrading
+
+We recommend that you pin the version of the Chart that you deploy. You can use the `--version` flag with `helm install` and `helm upgrade` to specify a chart version constraint.
+
+This project uses [Semantic Versioning](https://semver.org/). Changes to the version of the application (the `appVersion`) that the Chart deploys will generally result in a patch version bump for the Chart. Breaking changes to the Chart or its `values.yaml` interface will be reflected with a major version bump.
+
+We do not recommend that you upgrade the application by overriding `image.tag`. Instead, use the version of the Chart that is built for your desired `appVersion`.
