+## Quickstart with Helm
+
+If you are looking to deploy all Gen3 services, that can be done via the Gen3 Helm chart.
+Instructions for deploying all Gen3 services with Helm can be found [here](https://github.com/uc-cdis/gen3-helm#readme).
+
+To deploy the indexd service:
+```bash
+helm repo add gen3 https://helm.gen3.org
+helm repo update
+helm upgrade --install gen3/indexd
+```
+These commands will add the Gen3 helm chart repo and install the indexd service to your Kubernetes cluster.
+
+Deploying indexd this way will use the defaults that are defined in this [values.yaml file](https://github.com/uc-cdis/gen3-helm/blob/master/helm/indexd/values.yaml)
+You can learn more about these values by accessing the indexd [README.md](https://github.com/uc-cdis/gen3-helm/blob/master/helm/indexd/README.md)
+
+If you would like to override any of the default values, simply copy the above values.yaml file into a local file and make any changes needed.
+
+To deploy the service independant of other services (for testing purposes), you can set the .postgres.separate value to "true". This will deploy the service with its own instance of Postgres:
+```bash
+  postgres:
+    separate: true
+```
+
+You can then supply your new values file with the following command:
+```bash
+helm upgrade --install gen3/indexd -f values.yaml
+```
+
+If you are using Docker Build to create new images for testing, you can deploy them via Helm by replacing the .image.repository value with the name of your local image.
+You will also want to set the .image.pullPolicy to "never" so kubernetes will look locally for your image.
+Here is an example:
+```bash
+image:
+  repository: <image name from docker image ls>
+  pullPolicy: Never
+  # Overrides the image tag whose default is the chart appVersion.
+  tag: ""
+```
+
+Re-run the following command to update your helm deployment to use the new image:
+```bash
+helm upgrade --install gen3/indexd
+```
+
+You can also store your images in a local registry. Kind and Minikube are popular for their local registries:
