 ### Version upgrade checklist
 
+These version numbers are hardcoded in Terraform or shell scripts. We need to periodically check them for needed updates. Our [video introduction](https://drive.google.com/file/d/13SR3M8IowYBa4Wp_YEcuAURZ74EcCYoc/) also talks about some of these.
 * Cloud Foundry Terraform plugin in every module in the API and Admin apps, [here for example](sandbox/providers.tf#L6).
 * The [terraform-cloudgov module](https://github.com/GSA-TTS/terraform-cloudgov/), the version of which is referred to serveral times in most modules, [here for example](sandbox/main.tf#16).
 * Cloud Service Broker (CSB) version in [the SMS](https://github.com/GSA/usnotify-ssb/blob/main/app-setup-sms.sh) and [the SMTP](https://github.com/GSA/usnotify-ssb/blob/main/app-setup-smtp.sh) download scripts of the usnotify-ssb repo.
-* SMS and SMTP brokerpak versions, also in the download scripts of the usnotify-ssb repo, along with with the [SMTP brokerpak project](https://github.com/GSA-TTS/datagov-brokerpak-smtp) itself.
+* SMS and SMTP brokerpak versions, also in the download scripts of the usnotify-ssb repo. (And we may have to help maintain the [SMTP brokerpak project](https://github.com/GSA-TTS/datagov-brokerpak-smtp) itself.)
 * The version of Redis used in deployed environment modules, [here for example](sandbox/main.tf#33). To upgrade, the resource must be destroyed and replaced. The versions supported are limited by Cloud.gov.
-
+* A required minimum version of Terraform is noted in every providers.tf file, [here for example](sandbox/providers.tf#L2). It would be best to keep it in sync with the version used by our CI/CD deployment pipeline. But, it does not need to be updated with every new Terraform release.
