-### Prevent an `Application`'s child resources from being deleted, when the parent Application is deleted
+### Allow temporarily toggling auto-sync
+
+One of the most common use cases for ignoring differences is to allow temporarily toggling auto-sync for an Application.
+
+For example, if you have an ApplicationSet that is configured to automatically sync Applications, you may want to temporarily
+disable auto-sync for a specific Application. You can do this by adding an ignore rule for the `spec.syncPolicy.automated` field.
+
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: ApplicationSet
+spec:
+  ignoreApplicationDifferences:
+    - jsonPointers:
+        - /spec/syncPolicy
+```
+
+### Limitations of `ignoreApplicationDifferences`
+
+When an ApplicationSet is reconciled, the controller will compare the ApplicationSet spec with the spec of each Application
+that it manages. If there are any differences, the controller will generate a patch to update the Application to match the
+ApplicationSet spec.
+
+The generated patch is a MergePatch. According to the MergePatch documentation, "existing lists will be completely 
+replaced by new lists" when there is a change to the list.
+
+This limits the effectiveness of `ignoreApplicationDifferences` when the ignored field is in a list. For example, if you
+have an application with multiple sources, and you want to ignore changes to the `targetRevision` of one of the sources,
+changes in other fields or in other sources will cause the entire `sources` list to be replaced, and the `targetRevision`
+field will be reset to the value defined in the ApplicationSet.
+
+For example, consider this ApplicationSet:
+
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: ApplicationSet
+spec:
+  ignoreApplicationDifferences:
+    - jqPathExpressions:
+        - .spec.sources[] | select(.repoURL == "https://git.example.com/org/repo1").targetRevision
+  template:
+    spec:
+      sources:
+      - repoURL: https://git.example.com/org/repo1
+        targetRevision: main
+      - repoURL: https://git.example.com/org/repo2
+        targetRevision: main
+```
+
+You can freely change the `targetRevision` of the `repo1` source, and the ApplicationSet controller will not overwrite
+your change.
+
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: Application
+spec:
+  sources:
+  - repoURL: https://git.example.com/org/repo1
+    targetRevision: fix/bug-123
+  - repoURL: https://git.example.com/org/repo2
+    targetRevision: main
+```
+
+However, if you change the `targetRevision` of the `repo2` source, the ApplicationSet controller will overwrite the entire
+`sources` field.
+
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: Application
+spec:
+  sources:
+  - repoURL: https://git.example.com/org/repo1
+    targetRevision: main
+  - repoURL: https://git.example.com/org/repo2
+    targetRevision: main
+```
+
+!!! note
+    [Future improvements](https://github.com/argoproj/argo-cd/issues/15975) to the ApplicationSet controller may 
+    eliminate this problem. For example, the `ref` field might be made a merge key, allowing the ApplicationSet 
+    controller to generate and use a StrategicMergePatch instead of a MergePatch. You could then target a specific 
+    source by `ref`, ignore changes to a field in that source, and changes to other sources would not cause the ignored 
+    field to be overwritten.
