+# set-project-id: Advanced Example
+
+### Overview
+
+This example shows how [`set-project-id`] function works on packages with
+sub-packages.
+
+Running `set-project-id` function on the example packed will:
+
+1.  Set `project-id`
+    [setter](https://catalog.kpt.dev/apply-setters/v0.1/?id=definitions).
+2.  Add `cnrm.cloud.google.com/project-id` annotation on
+    [Config Connector resources](https://cloud.google.com/config-connector/docs/reference/overview)
+    that don't have it.
+
+### Fetch the example package
+
+Get the example package by running the following commands:
+
+```shell
+kpt pkg get https://github.com/GoogleContainerTools/kpt-functions-catalog.git/examples/set-project-id-advanced
+```
+
+### Function invocation
+
+Invoke the function with the following command:
+
+```shell
+kpt fn eval set-project-id-advanced --include-meta-resources --image gcr.io/kpt-fn/set-project-id:unstable -- 'project-id=foo'
+```
+
+### Expected result
+
+1.  File setters.yaml will include `project-id: foo` setter.
+2.  In resources.yaml `my-test-project-second-bucket` StorageBucket resource
+    will include `cnrm.cloud.google.com/project-id: foo` annotation.
+3.  Kptfile in subpkg folder will include `apply-setters` mutator with
+    `project-id: foo` setter.
+4.  In resources.yaml in subpkg folder `iamserviceaccount-sample`
+    IAMServiceAccount resource will include `cnrm.cloud.google.com/project-id:
+    foo` annotation.
