 ## Installation
 
--> **Version reference convention:** Replace `VERSION` in command and configuration examples with the Consul API Gateway version you are installing, such as `0.3.0`. In some instances, `VERSION` is prepended with a lowercase _v_. This indicates that you must include the `v` as is part of the version, for example `v0.3.0`.
+1. Set the version of Consul API Gateway you are installing as an environment variable. The following steps use this environment variable in commands and configurations.
+
+```shell-session
+$ export VERSION=0.3.0
+```
 
 1. Issue the following command to install the CRDs:
 
-   ```shell-session
+```shell-session
-   $ kubectl apply --kustomize="github.com/hashicorp/consul-api-gateway/config/crd?ref=vVERSION"
+$ kubectl apply --kustomize="github.com/hashicorp/consul-api-gateway/config/crd?ref=v$VERSION"
-   ```
+```

+1. Create a `values.yaml` file for your Consul API Gateway deployment by copying the following content and running it in the environment where you set the `VERSION` environment variable. The Consul Helm chart uses this `values.yaml` file to deploy the API Gateway. Available versions of the [Consul](https://hub.docker.com/r/hashicorp/consul/tags) and [Consul API Gateway](https://hub.docker.com/r/hashicorp/consul-api-gateway/tags) Docker images can be found on DockerHub, with additional context on version compatibility published in [GitHub releases](https://github.com/hashicorp/consul-api-gateway/releases). For more options to configure your Consul API Gateway deployment through the Helm chart, refer to [Helm Chart Configuration - apiGateway](https://www.consul.io/docs/k8s/helm#apigateway).
