-## Installation
+## Migration Strategy
+See this doc for [detailed migration steps](./docs/migrating-heroku-to-control-plane) from Heroku to Control Plane. Even if you are coming from a platform other than Heroku, you can still benefit from the migration steps.
+
+## System Prerequisites
+
+_Note, if you want to use Terraform with cpflow, you will start the same way below._
 
 1. Ensure your [Control Plane](https://shakacode.controlplane.com/) account is set up. Set up an `organization` `<your-org>` for testing in that account and modify the value for `aliases.common.cpln_org` in `.controlplane/controlplane.yml`, or you can also set it with the `CPLN_ORG` environment variable. If you need an organization, please [contact Shakacode](mailto:[email protected]).

 6. Install Control Plane Flow `cpflow` CLI as a [Ruby gem](https://rubygems.org/gems/cpflow): `gem install cpflow`. If you want to use `cpflow` from Rake tasks in a Rails project, use `Bundler.with_unbundled_env { `cpflow help` } or else you'll get an error that `cpflow` cannot be found. While you can add `cpflow` to your Gemfile, it's not recommended because it might trigger conflicts with other gems.
 
-7. You can use [this Dockerfile](https://github.com/shakacode/react-webpack-rails-tutorial/blob/master/.controlplane/Dockerfile) as an example for your project. Ensure that you have Docker running.
+7. You will need a production-ready Dockerfile. If you're using Rails, consider the default one that ships with Rails 8. You can use [this Dockerfile](https://github.com/shakacode/rails-v8-kamal-v2-terraform-gcp-tutorial/blob/master/Dockerfile) as an example for your project. Ensure that you have Docker running.
 
 **Note:** Do not confuse the `cpflow` CLI with the `cpln` CLI. The `cpflow` CLI is the Control Plane Flow playbook CLI.
 The `cpln` CLI is the Control Plane CLI.

 ## Configuration Files
 
 The `cpflow` gem is based on several configuration files within a `/.controlplane` top-level directory in your project.
