+There are other additional predefined environment variables we can also use:
 
 - `CI_DEPENDENCY_PROXY_USER`: A CI user for logging in to the Dependency Proxy.
 - `CI_DEPENDENCY_PROXY_PASSWORD`: A CI password for logging in to the Dependency Proxy.
 - `CI_DEPENDENCY_PROXY_SERVER`: The server for logging in to the Dependency Proxy.
 - `CI_DEPENDENCY_PROXY_GROUP_IMAGE_PREFIX`: The image prefix for pulling images through the Dependency Proxy.
 
-This script shows how to use these variables to log in and pull an image from the Dependency Proxy:

+
+  To generate these files from the GitLab repository, run:
+
+  ```shell
+  bundle exec rake gitlab:usage_data:generate_metrics_dictionary
+  ```
+
+  The Metrics Dictionary is based on the following metrics definition YAML files:
+
+  - [`config/metrics`]('https://gitlab.com/gitlab-org/gitlab/-/tree/master/config/metrics')
+  - [`ee/config/metrics`](https://gitlab.com/gitlab-org/gitlab/-/tree/master/ee/config/metrics)
+
+Each table includes a `milestone`, which corresponds to the GitLab version when the metric
+was released.
