 ## Release Process
 
-1. Update version in [CONTROLLER_VERSION file](https://github.com/project-codeflare/multi-cluster-app-dispatcher/blob/main/CONTROLLER_VERSION) to the new release version.
+1. Run the [mcad-release.yml](https://github.com/project-codeflare/actions/workflows/mcad-release.yml) action.
 
-2. Once CONTROLLER_VERSION file change merged , create the release branch against the main as `release-<version>`.
+2. Verify that [mcad-release.yml](https://github.com/project-codeflare/actions/workflows/mcad-release.yml) action passed successfully. This workflow will create release branch and GitHub release tag.
 
 3. The release branch then trigger the [image build/push pipeline](https://app.travis-ci.com/github/project-codeflare/multi-cluster-app-dispatcher/branches) and push the image to [mcad-controller quay repository](https://quay.io/repository/project-codeflare/mcad-controller?tab=tags) with specified release version tag.
 
-4. Create a new release on [Releases page](https://github.com/project-codeflare/multi-cluster-app-dispatcher/releases) by creating a tag with same value as in CONTROLLER_VERSION file formatted (with v prefix) , provide proper release title and description.
+4. Verify a new release is created on the [Releases page](https://github.com/project-codeflare/multi-cluster-app-dispatcher/releases) .
 
 5. The latest release changes should also reflect in the [mcad go package module](https://pkg.go.dev/github.com/project-codeflare/multi-cluster-app-dispatcher).
