 The public API guard provides a Bazel target that updates the current status of a given package. If you add to or modify the public API in any way, you must use [yarn](https://yarnpkg.com/) to execute the Bazel target in your terminal shell of choice (a recent version of `bash` is recommended).
 
 ```shell
-yarn bazel run //tools/public_api_guard:<modified_package>_api.accept
+yarn bazel run //packages/<modified_package>:<modified_package>_api.accept
 ```
 
 Using yarn ensures that you are running the correct version of Bazel.
 (Read more about building Angular with Bazel [here](./BAZEL.md).)

 If you modify a public API, you must accept the new golden file.
 
 
 To do so, execute the following Bazel target:
-  yarn bazel run //tools/public_api_guard:forms_api.accept
+  yarn bazel run //packages/core:core_api.accept
