+This example shows how to override only a single item (file) under `data`.
+
+Follow this example by taking these steps:
+
+* Use the `verbatim` key, rather than `value`.
+This helps pass through characters such as newlines or quotes so that they are unaffected.
+* You must escape the dot in the filename in the `path` key as shown, or
+ you can write the path as `data["endpoints.yaml"]`.
