+## Helm Charts
+This repo contains a `charts` directory that contains the various charts that are used to deploy the Hedera-The-Graph node to a Kubernetes cluster. To get started first install the helm repo:
+```
+helm repo add hedera-the-graph https://hashgraph.github.io/hedera-the-graph/charts
+helm repo update
+```
+
+Then you can install the chart with the following command:
+```
+helm install [RELEASE_NAME] hedera-the-graph/[CHART_NAME] -f [VALUES_FILE]
+```
+
+**CHART_NAME** is the name of the chart you want to install. The available charts are:
+- **hedera-the-graph:** An umbrella chart that installs all the necessary components to run the Hedera-The-Graph node. More information [here](https://github.com/hashgraph/hedera-the-graph/tree/main/charts/hedera-the-graph)
+- **hedera-the-graph-node:** An optimized graph node for the Hedera network.
+-  **hedera-the-graph-auth-layer:** An umbrella chart that installs both the `auth-layer-proxy` and the `auth-layer-server`. More information [here](https://github.com/hashgraph/hedera-the-graph/tree/main/charts/hedera-the-graph-auth-layer)
+- **auth-layer-proxy:** An EnvoyProxy that acts as a reverse proxy that forwards requests to the configured index node, and also verifies the JWT token using the configured authentication server. More informoation: [here](https://github.com/hashgraph/hedera-the-graph/tree/main/charts/auth-layer-proxy)
+- **auth-layer-server:** A KeyCloak server that is pre-configured to work with the `auth-layer-proxy` to generate and verify JWT tokens used for protecting the index node. More information [here](https://github.com/hashgraph/hedera-the-graph/tree/main/charts/auth-layer-server)
+
+**VALUES_FILE** is the path to the values file that you want to use to configure the chart. The values file should be a yaml file that contains the configuration for the chart. The available configuration options for each chart can be found in the chart's README file of the respective chart, linked above.
