-#### CLI/UI Support
-
-It should be easy to enable manifest hydration via the CLI or the UI. 
-
-Consider the following app:
-
-```yaml
-apiVersion: argoproj.io/v1alpha1
-kind: Application
-metadata:
-  name: dev-west
-spec:
-  sources:
-  - repoURL: https://github.com/argoproj/argocd-example-apps
-    helm:
-      valueFiles:
-        - $values/values-dev.yaml
-  - repoURL: https://github.com/argoproj/argocd-example-apps-values
-    targetRevision: main
-    path: environments/dev/west
-    ref: values
-```
-
-```bash
-argocd app dev-west enable-hydrator --target-branch environments/prd --target-path west --primary-source-index 1
-```
-
-The `--primary-source-index 1` is necessary to make the Helm values repo the primary source of truth for the app, i.e. we will track that branch as the source of new dry commits for hydration.
-
-The command will need to print the following instructions before actually making the change:
-
-```text
-To finish enabling manifest hydration, you will need to commit changes to git. In the meantime, auto-sync should be disabled.
-
-This Application is managed by an ApplicationSet. If you have not configured the ApplicationSet to ignore the auto-sync setting, auto-sync may be re-enabled automatically.
-
-Continue to disable auto-sync (we will re-enable it later)? [Y/n] Y
-
-Waiting one second to make sure the change applied... success, auto-sync is disabled!
-
-Before finalizing the change, please commit the following to the `.argocd-source` file in https://github.com/argoproj/argocd-example-apps-values under the `environments/dev/west` directory (if multiple apps use that directory, you can use `.argocd-source-dev-west`).
-
-sources:
-- ref: values
-- helm:
-    valueFiles:
-    - $values/values-dev.yaml
-
-These settings can no longer be managed in the Application CR and must instead be committed to git.
-
-After committing the change, confirm to continue. If you choose to cancel, we will pause to re-enable auto-sync. [Y/n] Y
-
-Updating the Application CR to use manifest hydration. The Application may appear unhealthy for a moment while the manifests are initially hydrated and pushed to the environments/dev branch...
-
-The Application has been updated and is now synced to environments/dev. Waiting for the Application to become healthy...
-
-The Application is healthy, and migration is complete!
-```
-
-The CLI should have a mode to do the git push bit on the user's behalf to avoid the interactive mode.
-
-The final Application manifest should look like this:
-
-```yaml
-apiVersion: argoproj.io/v1alpha1
-kind: Application
-metadata:
-  name: dev-west
-spec:
-  sourceHydrator:
-    drySource:
-    - repoURL: https://github.com/argoproj/argocd-example-apps
-      targetRevision: main
-      path: environments/dev/west
-    writeTo:
-      targetBranch: environments/dev
-      path: west
-```
-
-A similar user experience should be made available via the UI.
