 Usually a release of the Helper Web App will be accompanied by changes to the bicep code. In which case a new symantec release tag needs to be chosen (0.8.2 or 0.8.5 etc).
 There is a [GitHub action workflow](https://github.com/Azure/AKS-Construction/actions/workflows/release.yml) which is initiated manually but automates the release, all that needs to be provided is the new release tag.
 
+- If you are not a member of the [AKS Construction Admins](https://github.com/orgs/Azure/teams/aks-construction-admins) or [AKS Construction Maintainers](https://github.com/orgs/Azure/teams/aks-construction-maintainers) groups, please ask a member of either group to be available to review your deployment - **you won't be able to complete the release without their review**
+- Trigger the [Release bicep and helper](https://github.com/Azure/AKS-Construction/actions/workflows/release.yml) action, incrementing the release version by 1 (e.g. 0.10.1 :arrow_right: 0.10.2)
+- Wait for the workflow to run to completion
+  - If any errors occur, examine the output of the job that failed and troubleshoot the issue(s). You may need to submit a fix via PR, which will require an additional person to review and approve
+  - If there are no errors, the action will pause on the "Deploy Web App to Prod Pages" job - you will need a repo admin or maintainer to review and approve this job to create the final release
+- Navigate to the [Releases](https://github.com/Azure/AKS-Construction/releases) page and check your new release has appeared
+  - It should be showing with the "Pre-release" label
+  - Edit the release, scroll to the bottom of the page and select "Set as the latest release" and save the change
+- Open that [AKS Construction helper](https://azure.github.io/AKS-Construction/) and verify that your release is now the current release

 ## Releasing just the Helper Web App
 
 Occasionally there will be UI improvements that we want to release that do not have any dependencies in a new release.
